Quake Arena Arcade has a lot of potential. But seeing as the developers dropped support for this title, I'm leaning toward Quake Live.
- Bethesda dropped all support (so it seems).
- There's still people who can't access online multiplayer.
- There's still a lot of lag.
- There's still a bunch of bugs and glitches present in the game.
- There's minor differences between how the game plays between Quake Live and Quake Arena Arcade. For example; the Nailgun doesn't ricochet off walls, the Plasma Gun fires slower, and the character speed is bit slower, etc. That's all nitpicking of course.
- Less available game modes to choose from.
- Less maps.
- Less customizations.
- Quake Live is free.
Yeah, the list goes on... I still love QAA but it could be so much better. Lets look at the bright side though!
- Quake for XBLA!

- Great graphical update!

- Great sound!

- New exclusive maps (but to be honest though they're quite bland)!

- IT'S QUAKE!
