Hmmm... The old Amiga housed the first few good PC games I remember.
Top Hat Willy was a great platformer, Crystal Caves was a pretty good action platformer... And Defender of the Crown... Hehehe... One of the first games to boast "stunning full-colour visuals" or something similar.
But on Windows... Age of Empires I, naturally, and Monkey Island was especially memorable. Then there was The DIG... Amazing game. One of the first games with voice acting, I think.
Oh, and I'll never forget The Neverhood - clay animation at its finest. And it was such an odd game - like something out of a Terry Pratchett novel.
Then Sims came along... I bet most of you have played the original Sims at some point or another.
It was great because everyone played on the same account, in the same Sims save, in the same neighbourhood... That's really how the game was meant to be played.
Fast forward a few years... Age of Empires 2, Dungeon Siege (much better than the sequel), Oblivion. Those are the games that stand out off the top of my head, anyway - there were many more in between.
Anyway, thanks for the trip down memory lane. Wow, thinking back to Amiga days makes me feel old.
