By fixing my post that way you seem to negate the Voip issues, which is wrong. The voip is horrible most of the time. I played with both mrb and kube last night, most of the time one or the other sounded like he was underwater.
Yeah, most demo's don't have a way to set up custom matches. No surprise there.
If by "not fun at all multiplayer game" you're referring to AvP... I got that vibe, but I liked AvP (though not enough to get it by myself to play with random people) and, as of now, I'm not too impressed with DS2. In AvP, each race would have a different amount of players to balance it out a bit. In DS2, humans have 4 players, necromorphs have 4 players (though I think they get a few computer controlled necromorphs... but why not just have them be player controlled?). Which is bad because humans are vastly more powerful than necromorphs, though that may be because controlling a necromorph is a bit confusing. Even if you knew how to control a necromorph, a human can still kill a necromorph in one or two shots, they die so often, there isn't even health for necromorphs... it's like they designed them to be cannon fodder. I would be slashing on a human for 20-30 seconds and he still wouldn't die. Of course, humans respawn with a health pack (and a stasis) and necromorphs will occasionally drop more health packs when they die, so that may be a part of that. Another issue is spawn time. Humans have 5 second delays (I think) and can move instantly once they spawn. Two of the three necromorphs can respawn instantly, the third has a 5 or so second wait, but it really isn't instant because you have to pick your spawn point and then wait for it to slowly crawl out of the panel and if a human happens to come around the corner as you're crawling out (with no control of the character) he can easily shoot you and kill you before you can even move. I get that it's kinda by design to prevent necros just spawning on top of the humans, but several times I'd pick an isolated area, but a human would show up before I was done spawning and cut my legs off.
A few things I wish they would've done differently. Less humans or more necros. Faster respawns for necros, by streamlining the spawning process and cutting out the crawling out of the woodwork. Slower respawn for humans. Although... my opinions could change if I had more time playing as a necro. Apparently necros can lock humans in a melee battle, but I could never figure out how to do it. To me, it kinda seems they copied the dynamics straight over from the single player game and it just doesn't feel like it works well in a multiplayer environment.
