Shall I buy NFS Shift, or Shift 2 Unleashed?

[Freeman]

I'm currently thoroughly enjoying F1 with my G27 but am looking for more touring car type racing.

Should I be getting Shift 1 or 2?

I know there are plenty of sims out there offering touring cars, but I'm looking for something a bit more arcadey like F1.

Cheers.

I have all the DiRTs and have also played rFactor and LFS - I'm just looking for something a bit more updated and maybe a bit more acardey.
