I have several bars that I like to frequent in games, I just wish they were better implemented. It's good to be able to buy drinks and pick up on gossip but you should be able to do what people go into bars to do - socialise. It'd be cool if you cold gain points with people if you buy them drinks and make merry as well as losing them for being a cock. Also, you might be able to get that buxom serving wench drunk and then...
Ahem, sorry...
So yeah, my favourite bars in games!
1) Chora's Den (Mass Effect) - Music, drinks and saucy Asari dancers. What's not to like? Also if I criticise it, Fist might get one of his Krogan bouncers to kick my head in!
2) Afterlife (Mass Effect 2) - Music, drinks and saucy Asari dancers. What's not to like? Also if I criticise it, Aria might kick my head in!
3) Purgatory (Mass Effect 3) - Music, drinks and...yeah, you get the picture!
4) Moriarty's Saloon (Fallout 3) - Owned by a complete knobend but it does have a friendly, if slightly rotting bartender. And then there's Nova...Jesus, I really have to get laid...
5) Any of the Skyrim taverns - I love the aesthetic of the buildings in Skyrim and the taverns are great examples of it and the whole Norse mythos. Wood. Stone. Fire-Pits. Entire cows on spits. Booze. I love it!
