G25 works fine with Euro Truck Sim here. Still get the shitty SCS steering problem when going more than a certain speed (turn too much and the whole thing starts going sideways, and when you eventually straighten it up you get a kind of steering spike), annoying but you get used to it.
Theres talks of an expansion pack coming some time with more areas to drive and even the UK. Not sure how they'll manage the traveling across the channel (ferry, train?) and the switch to left hand side driving, but we'll have to wait and see I guess.
It's still a typical SCS game though, plenty of flaws but fairly enjoyable I guess.
