Good ones last night - Species team DM is a good one.
I'm not sure how long AvP will last as one of our played titles as there aren't that many maps, but the ones there are good ones. Game modes keep it alive too. There are also some big inconsistencies with hand to hand combat, although its a nice-to-have in the game as it give you (as an alien or pred) at least another option or chance of taking someone down - but it generally comes down to 'who blocked first' or who can get the charged hit in first.
The inconsistencies I talk of are; as a marine, melee doesn't always make aliens stumble, yet sometimes it does - it might be a timing thing I don't know but this causes me a major gripe - not every fight should be the same, but the marines should have a margin of hope somewhere like if a melee attack is blocked by them, a counter attack should always make the enemy stumble. Between Aliens and Preds its slightly different as both can block each others light attacks forever, but it comes down to what I said earlier - who can get in that charged attack or who blocks first.
The best or rather, the most successful class is of course, aliens - because;
1. They heal themselves. Quite quickly to boot.
2. They can see through walls, albeit not that far, but its further than any marine or pred can.
3. They're fast.
4. They can climb on anything.
5. They can insta-kill from behind
6. They move almost silently.
7. They can hide in the dark.
The only downside I see is that they're weak so in a killzone, your dead meat, but think of how fast you get back into the action compared to a marine or pred. You could spawn the other side of the map and be back in less than 10 seconds to wipe out any stragglers.
The most satisfying class, is Predator. Specifically spear kills, they are some of the best I've ever seen. Disc kills are quite fantastic once done right. Shoulder cannon is total hax, and so are mines, but I guess they had to put in some other tools for the pred to use.
Marine class is simple, run and gun. Its nice to be one of two marines against preds and aliens as you feel as though your at a disadvantage, but your not, well, you are, but only from behind. Meet an alien or pred head on and you're ready to fire - the ball is pretty much in your court if you can aim or keep track of the enemy, with only speed being a problem.
I'll be honest, I'm not big on the Predator hunt mode, because the pred simply isn't strong or stealthy enough. Even cloaked a sharp marine can shoot in the head area and get a kill. Your only hope is to catch a marine on his own and even then you need to get behind them because if they've got a shotty, your fucking screwed - first shot your stumbling on the floor, next shot your dead :/
Anyway, I'm sure there is lots more fun to be had on this so lets just enjoy what we've got!
