I'm surprised there are gamers who never heard of Flashback or Out of This World
You guys aren't that young
I'm not sure if Zak McKracken and the Alien Mindbenders is weird, but it is strange and one of the funniest games I've played. It's a LucasArts SCUMM game where aliens are undercover at the phone company trying to take over the world using a stupidity machine (lowers the IQ of humans). Some odd things are two of Zak's friends can fly to Mars in their van and a two-headed squirrel makes an appearance in Washington (that's my current avatar). I never did finish the game as it can be challenging, and it's possible to run out of money which happened to me. I took too many flights to the wrong locations which maxed out my credit card. You can win the lottery in the game but after reading a hint guide I still found that to be difficult
Seaman probably counts as weird
I like that game even though it's mostly just managing an aquarium. Unfortunately, I ran out of food when Seaman was only a day or two from being released into the wild so he/it died :'(
