It could be, I dunno. I have always been a big Rare fan, but I am worried. I can make excuses for the last few games to come out, but I can't make excuses for PDZ if it sucks. Of course I won't trust a single review, I will have to wait a long LONG time until I can sit down myself, eased by the sudden lightness of my wallet, and play the game
PDZ has some pretty fun multiplayer, I'd rent it to see if you like it first though. The maps themselves are huge, and scale down to the number of players. The map hallways for the scaled down map can be randomized, so some of the hallways to a flag may be blocked off in one session, and not another. Killing is a bit slower than Halo 2's multiplayer, this is due to everyone wearing armor, so its harder to get a headshot right off the bat (i.e. you have to knock off the helmet then shoot the head). My only real disappointment is the bots, no bots personalities, and you can't choose which part of the map to play when its scaled down.
There were a bunch of different kinds of bots in the first Perfect Dark, each with its own unique personality. VengeSim, KamikazeSim, PeaceSim, etc. I don't remember all of them or what they do, but it was pretty fun experimenting with them.
