Official last game you've beaten thread

Far Cry 3 yesterday and Far Cry 3 Bloodstone (few minutes ago)

Machinarium

Half-Life 2: Episode One

Bioshock: Infinite

Unmechanical - Wasn't what I expected, but it was mostly nice. Pretty sure I didn't solve one of the puzzles the way you're supposed to, but other than that puzzle, it was mostly intuitive. Short, but a nice game.
Samorost 2 - Thought I'd played this one through years ago, but it didn't seem as familiar as I'd thought. Another very short game, and the save system sucks, but it's semi-early-days Flash, so... yeah. Not bad though.

I'd be more interested in what game did you last get all the achievements on, but anyway, same game!
Fortix :P

Alan Wake... Just finished yesterday evening. In the last few days, have finished Thomas was alone, Braid, DLC Quest, Hector Ep 1 & 2, Puzzle Agent 1&2, and sleeping Dogs. Thats a good big dent to my Ever increasing Back log.
Right now going to finish Walking Dead that I left in between 4th Chapter for no reason.

Medal of Honor from Origin bundle ;x

yesterday Fez and Crysis 2 (X360), today Crysis, tomorrow Crysis Warhead

Giana Sisters Twisted Dreams. Boss battles (mostly the final) was fairly frustrating, but other than that a great and enjoyable platformer.

Edna & Harvey: Harvey's New Eyes - Weird game with very good black humour. In the first chapter some things can upset religious people but I think no lines have been crossed. 8+/10

McPixel - One of the worst "games" I've ever played. There's absolutely nothing good in it. Maybe just that it's short. Humour is very, very low (unless one likes laughing at putting bones inside a cow's anus or peeing on aliens), graphics are terrible, music is annoying, the whole "game" is pointless and stupid, there's no plot, shall I say more? It's terrible. 1/10

Penny Arcade on the Rainslick Precipice of Darkness 4

Zombie Bowl-O-Rama -- good for a bit of fun, bad for trying to get very high scores or expecting normal bowling physics to matter

Tomb Raider 2013

A single playthrough of Europa Universalis 4, if you call that finished... otherwise it'd be Bastion

Who Framed Roger Rabbit

Bioshock Infinite and Lara Croft Guardian Of Light

Botanicula, need to go back for 100% achievements. I love the style 10/10 for me

Saints Row 3 and Saints Row IV

Deadlight - I expected a platformer shooter and I got a platformer survival which was a pleasant surprise. The game is good. It would be very good if not for tons of bugs. It's also short. I like that there's actually a lot of things to collect and unlock. Like I said, it's a good game. 7+/10

Batman: Arkham Asylum (for the second time, but now on Hard and with all collectables)
Launched it to check on GFWL stuff, ended up playing half the game yesterday. Finished it today.

Faerie Solitaire - Not to 100% as far as Steam achievements go, but I've done the adventure mode. Will finish off the cheeves eventually.

I found the card-playing of element the game addictive. The storyline was forgettable, didn't know or care what was meant to be going on. The eggs and pets is just weird, don't know who came up with that or why.

GTA V now. Took me 30 hours to complete the story, with 80% overall completion. Now time to have fun, blow shit up, and work on 100%.

Shadowrun Returns.

Tomb Raider: Underworld - It's the best TR game from the "old" series. The most technologically advanced and it has the best gameplay of them all. I especially like the atmosphere and graphics. I don't like the outdated fighting/shooting mechanisms and the fact that camera sometimes goes crazy. All in all I recommend it to everyone along with Legend and Anniversary. 8/10
