All the games I have been able to play thus far are very fun, and very promising! I actually own both Marble Blast Ultra, on the 360 had it since i bought my 360 and I have Marble Blast Gold for the pc as well, playing Think Tanks on Instant Action actually made me buy the retail Think Tanks. While i was looking at some games listed on the Garage Games website I found a game that peaked my interest its called Dark Horizons: Lore Invasion and it has been released for free. I play it and its a Mech game like starsiege, seems to have the skiing tribes has, and also has a Jet Pack, it would seem most games on the Torque engine all cary the same feel of Tribes its really amazing. The skiing is a little like Tribes 1 skiing though.
Anyhoo anyone interested in giving Dark Horizons: Lore Invasion a try its a free download and it is the full retail version it can be downloaded here:

Also the reason its been released for free is because its Sequel Dark Horizons: Lore Invasion 2 is going to be released on Instant Action as well.
I am really enjoying how open Garage Games is being with the beta testers.
So far I take everything back I said about browser-based gaming.
