I poll you Sony fans make a choice just type the name of the game you will buy out of Resistance 2, Kill Zone 2 or both.

Both.

Both, unless the reviews for Killzone 2 suck.

Probably both. R2's online co-op makes it a must buy for me (and I need to find out what happens next), and I REALLY want KZ2 to be good. I thought the premise of the first was fantastic, and the presentation of the second is turning out great. I can only hope that the other problems of the original are fixed in the sequel (linear and unoriginal levels, spotty Ai being the cheif problems).

Resistance 2 is a no-doubt day-one purchase for me. Killzone 2 will have to have good reviews.

Neither... Buy MGS4

It's still too early to see any reviews or extensive gameplay... but i say both!

Probably both. Resistance 2 8 player co-op seals the deal for that game. Killzone 1 was pretty decent, but way too ambitious for the PS2 hardware. If they can fix the shortcomings of the original (AI, framerates, level design), then the second should be great. Killzone 1 multiplayer was pretty fun too. Hope they still have bots in the game.

Resistance for me, unless KZ turns out awesome.

I'd say just Resistance. Killzone was mediocre, so I don't expect much from 2.
