The interface is pretty simple and straightforward. The games are not flash. They are using their torque engine. Just some of the UI in the browser interface is flash.
For the most part the sample games are pretty bland. Marble Madness can be pretty fun. A LOT of the people who have signed up are mostly interested in this Legions game which they call a "spiritual successor" to Tribes. Although GG seems to love hocking the Tribes similarity to grab many of its audience, they keep saying you shouldn't expect Tribes. I say quit calling it a spiritual successor then.
It will be interesting to see how they handle some of the complexities like dedicated servers and all. many of the fans wanting Legions will want the same type of features they expected from a stand alone PC game. This comment was edited on Mar 7, 01:18.
