The Baldur's Gate series. Hands down. True, the original game is very old now (1998) and not many people have heard of it, but loads of people will tell you it's the best RPG of all time. So good in fact, that they very recently re-released the first game in the form of an 'Enhanced Edition', which brings it up to modern standards. It was a 3rd party company who got the license to do it, and they made it a very community-based thing, creating a forum and asking the fans - myself included - what they wanted to see updated/introduced into the updated version. Great experience I must say, even if my suggestions made no difference whatsoever
If you like fantasy, and games which go far beyond simple hack-and-slash, then I really recommend it. Luckily, the new game is really well priced ($13 for PC/Mac and $10 for iPad). If you're not sure, have a look on YouTube for 'Let's Play's, there are probably 100s out there!

Favourite game? Hmmm. at the moment, the online Star Trek game. But if we are on about consoles, Knight Rider 1 and 2 for the ps2.

The Mass Effect Series and the Fallout Series
