I haven't played enough games to have a top 10. Or a top 5. Sims 3 is the game I keep coming back to, Tomb Raider Legend is probably my favourite although I won't replay it.

OH in regards to Avatar, my copy hasn't even been dispatched lol. I have seen the series before yeah, I mainly wanted the box set because my memory of Books 1 and 2 is kinda rusty. Well... very rusty :P
