Indie wise this is what I have been playing the last few months:
- And Yet it Moves
- Bastion
- The Binding of Isaac - Dungeon crawler of sorts, one life for whole run through game
- Bit.Trip Runner (Awesome soundtrack)
- Capsized
- Cave Story+
- Cogs
- Cthulhu Saves the World
- Demolition Inc
- Dust Force - A bit like Super Meat Boy in gameplay
- Galcon Fusion
- Grid Runner Revolution - Another refresh from a Jeff Minter classic from the man himself
- Jamestown (Awesome shoot em up)
- Magika
- Minecraft
- Night Sky (Think I got this as part of the Humble Indie Bundle - Not played as yet)
- Payday: Heist - Maybe not the usual feel of an indie game and servers are starting to die off now
- Really Big Sky
- Realm of the Mad God - Free to play on Steam, 8bit like mmo shooter game, really good fun
- Satazius - Great hark back to the 90's shmups of the SNES/Mega Drive era (R-Type like)
- Scoregasm - Shoot em up, more in the ilk of Geometry wars)
- Space Giraffe - Jeff Minter genius

- Super Meat Boy
- Terraria - Some will say its a Minecraft rip-off, it borrows a lot but a great game

- Torchlight
- Trine 1 & 2
- VVVVVV - Great game and great soundtrack
- World of Goo
In the last year or so I have switched heavily to indie gaming. I think it offers a lot more in the way of something new/different/challenging than the usual rehash and packaged games that are coming out of the big studio's at present. Only so many rehashes of an FPS or RTS that's the same old as it has always been with a new game style or skin on it.
Just something about what they label as AAA games that just don't interest me enough to spend £30+ on them.
Out of the list above the ones I would recommend over the rest (not saying they are bad games there

)are:
- The Binding of Isaac
- Bit.Trip Runner
- Dust Force
- Scoregasm
- VVVVVV
- Super Meat Boy
- Satazius
- Jamestown
Really playing these on an almost daily basis
