Just saw this on Amazon, there doing a pack of these games on disk i guess for people who don't connect to there 360's to the internet. It will also save you 10 dollars if you have never bought any of them just thought i would let people know here's the link  http://www.amazon.com/pack-Limbo-Trials-Splosion-Xbox-360/dp/B004QIY0Y4

I just grabbed Trials HD and 'Splosion Man in XBLA's sale last week.  Damn fine games, if you have an Xbox 360 you want both of these.  They are balls hard, but in that "Oh fuck you, I WILL beat this level" kind of way.   I recommend those games highly.

Too bad i already own 2 of these games...

this is a heck of a deal. all three of those are pretty great.
