Yes Bish, the game is great fun, and as stated, it's been given a bit of a face lift graphically... and yes a bit dated, but I've always been a fan so it was a must buy.
I could never get on with controllers, but playing it on the pc is much better, (for me).
It's all going on up there on Reach... we are getting ready to give the Covenant forces a bit of a kicking!
