BL2 GOTY Edition is only $8 on Amazon (Steam code for PC works on Mac)

Note this is for the digital download version. I've played the crap out of it on 360, but decided to give it a whirl again. Not sure why they charge so much more for the Mac version, as the PC code works cross-platform. Highly recommended game if you like looting shooter style games.

Playing this game through for the 4th 5th (or maybe even 6th?) time - it's that good. The Tiny Tina DLC is incredible, as well. Highly recommended!

There's also pretty steep Borderlands sales at GameAgent at the moment.

I love FPS games, and I love Diablo II (have probably logged over 500 hours on the latter over the years). However, I just can't get into Borderlands. I can't really articulate why, but they just haven't grabbed me in the way that other games have.
