Gamespot has reviewed Dirt Track Racing 2 by Ratbag, and summarises the title with..
"Dirt Track Racing 2 has its share of high and low points, same as any game, but the most important complaint you can raise against it is that it's essentially the same game Ratbag has been making for years now...
..If, on the other hand, you've never played any Ratbag games and are looking for a solid racer with an unusual subject and unusual quality for a budget game, Dirt Track Racing 2 is well worth trying out. "
Something to add to this is that Ratbag is doing something different, with Ikon, and perhaps some other games in production. Anyway, read the article here.
