It's only forever; not long at all...
Mine, hmm. I love Age of Mythology and the expansion pack for it, it gives hours of fun in ever changing scenarios, there is a very large scope to cheat, and an even larger scope to mod it. I haven't done any mods for a while, but I like playing around with the Editor. I also really like the Gothic series, this has endless cheats to play around with for some really cool effects and changes to how your character works. Theif 2 is also good, although difficult, and it's great fun sneaking around and causing chaos. What are your favourite games?
