Oh just FYI
TrackMania˛ Stadium is in open beta on Steam. I played it for an hour last night and enjoyed it for what it is -- a little racer with really zany tracks and an extremely simple physics model. It was designed for keyboard. Stadium supports a controller LS-steer, LB-brake, Rb-gas, with analog steering but still binary gas/brake. (It feels similar to a free predecessor TM: Nations Forever, on steam.)
