The 90’s was my college years, and also the era of Cheapass games and Star Fleet Battles for me and my friends at the time.
Star Fleet Battles (1990) - Long, convoluted game with rulesets that read like legal documents, but coined one of my favorite rules regarding a weapon called a Mauler, noting that “it cannot be swung around the board, à la lightsabre.” Good simulation game of starship combat in the Star Trek universe (though the whole fighting at warp speed aspect seemed silly).
Nuclear Proliferation (1992) - Standalone expansion to Nuclear War (1965) which added a lot of new features. This is a game I originally played in high school and it was silly fun, so I picked it up myself later. Didn’t really hold up and now it just sits around.
Once Upon A Time (1993) - My wife saw it in a small game store we stopped by one day and bought it to support a small business. We’ve never played it.
Blood Bowl 3rd edition (1994) - Saw part of a tournament of this being played at a game store in college and was instantly hooked on the idea. Picked it up when I could and introduced it to my high school friends over the summer break and played our own tournament. Was a lot of fun.
Settlers of Catan (1995) - A game that seemed to be in everyone’s collection for a time. Still have it, but haven’t played it in years.
Condottiere (1995) - Only got this two Christmases ago and it has yet to hit the table. Wanted it ever since seeing SU&SD’s rules explanation video.
Mystery of the Abbey (1995) - One of the first “modern boardgames” I purchased after a random stop at a billards and darts store sometime in the 2000’s. Choice was between this and Shadows Over Camelot (which I got later). Kind of a Clue variant, where you need to find the murderer from a list of monks who each have different characteristics. What I like is that to get information, you can ask almost any question you want from the other players you encounter, but if they answer, they get to ask a question in return, and with it all being public, the other players can overhear and get info as well. Also that you can make declarations about a characteristic the murderer has and at the end of the game, you get points for being correct about the characteristic, meaning the player who actually accused the correct suspect may still lose the game if someone else correctly stated enough characteristics. Still love the game, just does not get played much.
Kill Doctor Lucky (1996) - One of (if not the) first Cheapass game. A reverse Clue, where the players are trying to kill Doctor Lucky while not being observed by the other players. Not bad, but can drag on too long.
Lord of the Fries (1998) - Another Cheapass game, trying to get rid of all the cards in your hand. Has a good humor to it. Kind of a more complex Uno. Fun enough.
Chinatown (1999) - Another one that I got interested in due to SU&SD, this time with their Let’s Play. Picked it up sometime last year, but it has yet to hit the table.
El Grande is not listed on BGG for me for the same reason as @pillbox mentioned. I have played it once. It is great. I hope to play it more soon.
