Tend to only play FIFA, Football Manager, and Forza these days. Used to be a fan of the likes of Command & Conquer - Generals, Acclaim's Constructor, Theme Park, GTA series, and Roller Coaster Tycoon.

Other titles I can recall spending a lot of time on: Monkey Island 1 & 2, Zak McCracken, Day of the tentacle, Indiana Jones series, Gods, and Broken Sword 1 & 2.

Also remember Runescape quite well. I used to play it back in the day, after being convinced by folk on the old IRC networks. Runescape was only in beta when I first started back in the very early 00's.
