A brief history of SlifkerGames.

      - 10/15/2020 - "Jungles of Maxtheria" released.


      - 03/05/2020 - At an Indienomicon meeting, there was a lecture by Chris Keeling who worked at "Wargaming Group, LTD" on a number of games for them like "World of Tanks" and "Master of Orion: CTS".  After the meeting when many of us walked to a nearby bar in downtown Orlando.  At the time we knew about the Coronavirus, but only a handfull of people in Florida had contracted it.  We were a little concerned, but at the time it was more of a west cost thing.  The politicians on TV were downplaying it which is why we had a meeting and then went to a bar in a group.  A week later Disney and Universal shut down which alerted us to this very real pandemic.  A couple weeks after that, the state of Florida shut down.

      - 11/08/2018 -  For the "Free Play Florida" event this weekend, I needed to get a banner printed up to put behind the booth.  This was a large format 6'x2' color banner so it needed a special printer.  I went to a nearby "Office Depot".  First it was printed on to paper, then 10 grommets were added to the outsides, then the white border was cut off.  Thanks goes to the two employees that stayed 15 minutes after close to make it happen.  The stand just came in today so I had a chance to see if it worked.  The picture below shows a test in the living room with tie-wraps attaching the banner to the poles.  It works great.

      - 11/06/2018 -  To get ready for the "Free Play Florida" event this weekend, I stopped by the Florida Mall in Orlando.  I just wanted to give a shout-out to the "T-Shirt Factory" for making our T-Shirts.  They have a kiosk and will make them while you wait.

      - Sept. 1985 - For a birthday in high school I got a case holder for my Atari 8-bit computer 5 1/4" discs.  At that time I had either a Atari 1200XL or Atari 65-XE (not sure which one) to play on.  The T-Shirt was what I wore to Kung-Fu classes that I was taking for self defense.

      - 1984 or 1985? - For Christmas 1984 or 1985, I got an Atari 1050 disc drive for my Atari 8-bit computer.  The 1050 was released in 1984 and at one point I had four of them daisey chained together.  The washed out T-Shirt was for the "Tampa Bay Bandits" of the USFL (United States Football League).  The USFL lasted for 3 seasons from 1983 to 1985.  I did get to go to maybe 3 games including the 1984 USFL championship game that was held at Tampa stadium 100 miles away.  The USFL Bandits was the one childhood thing I loved as much as Atari.  I even had a Loni Anderson poster on my wall in a "Tampa Bay Bandits" cheerleader uniform (OK, OK. She was in the TV show WKRP and was dating the actor Burt Renoylds.  He was a part owner of the team so I guess he talked her into doing a poster.)

      - 1982-1984? - This was me opening the package from the mail for an Atari VCS 2600 cartridge "Crazy Climber".  That was released in 1982.  Are you digging the funky hair yet?

      - 1982? - At "Walt Disney World" in Orlando, Florida, I entered an Atari VCS 2600 Pac-Man contest.  This was at "Lake Buena Vista" which is now called, "Downtown Disney" (and doesnot even look the same anymore).  It was a timed event inside a big tent they set up with dozens of systems playing the game at the same time.  We each had a time limit to get as many points as possible.  Everyone played the same game on the same settings.  People were coming and going all day long for several days.  When done, I got the current high score.  My name went up on the giant billboard so we left.  Minutes later someone else got a higher score which stayed that way thoughout the day.  At the very end of the day, my score fell to third.  Eventually, this was one of the top scores out of several thousand players.  After the event was over, we went back to get my free Atari VCS carts.  You can see the orange Tampa Bay Buccaneers ball cap, adidas T-Shirt, long jeans (back them I always wore long jeans no matter how hot it was outside) and 80s haircut that had to be "below the earline".  I looked so young, thin and naive.  Not to give out my current age, but this would have taken place when I was in middle school.  Good times.

      - 04/25/1982 - I entered an Atari VCS 2600 Pac-Man contest at the "Colonial Plaza Mall" in Orlando, Florida inside the Belk Lindsey department store.  The game was releaaed in March of 1982.  This was on the second floor in the eletronics section where not many people were around at the time.  The event had been going on for a few days, so when I was ready I went with my parents and grandmother.  The guy working the event at the Atari VCS 2600 asked if I wanted the easy game for kids (game 7?).  I said, "NO!".  Put it on game 6 which was the hardest (Pac-Man and the ghost moves at a running speed).  The reason was that the characters would move faster and thus I could get more points in the alloted time (Obviously, they can not allow you unlimited time or players would play all night long).  The game started and I got killed within the first 10 seconds.  After that, I played perfect and got the week's high score at the store.  When we went back a few days later to get the prizes (an Atari VCS 2600 system, a Pac-Man cartridge and some other carts), They told me I had the highest score at any of their stores.  They did let me swap the Pac-Man cart to another game as I already had Pac-Man.  Years later the mall was torn down along with the Belk Lindsey.  Not bad for a kid in middle school.

      - 1981 - This was my birthday in 1981 with some childhood friends.  I am on the right with the "Cat Diesel Power" hat on and the "Missile Command" T-Shirt playing an Atari VCS (It wasn't renamed to the Atari 2600 until over a year later.).  Looking at the joysticks, you can see the proper way to hold one is with the thumb over top of the joystick stud.  It is not how the guy on the left is holding it.  That was the middle school years.  Lots of Atari.
