Need help to chose some games.

Because LBP is an older title, it will go cheaper sooner too (on their Platinum line or whatever they call it). If I were you I'd get KZ2 now, OR wait a few months and then get Uncharted + LBP for the same price.

Yeah, LBP is under £20 right now.

Uncharted is an awesome game. Really high quality and a roller coaster ride, with a lot of variety. It has much in common with RE4 (without the horror and with a lot of pirates shooting at you).

If you're choosing between Resistance 2 and Killzone 2, I'd definitely go with KZ2. That game will blow your pants off!!! (don't bother downloading the demo, it's a poor reflection of the full game).
Both Resistance games are good but I actually preferred the 1st one. You can probably buy that very cheap.

And presuming you're a horror fan, don't forget about Siren! It's not just the best horror on PS3 but it's probably the best horror game of the current generation.
