I've played this for about 3 days now, I have my character to level 10. I'm enjoying the game, but there's something missing, and I feel like I figured out what it was today.
At first I thought it was because there's no real customization or changes to my character. There's no new skills, or abilities, or even weapons, really. Once I tried all (honestly just most) of the weapons, and I stopped dying, there hasn't been much incentive to play.
What's really missing is a goal. I know this game is in Alpha state, but I can't tell what the future holds for my character. I thumbed through the different class/builds/grid-thingy (boring!), but I'd like to see some future skills that adds some bad-assery to my character, if only I slaughter another 1000 guys, and another 10000 after that. Give me reasons to play besides "kill X of these monsters," or "complete X missions." Honestly, we've been there, and done that, and I don't really want to do that anymore.
I want my guy to get stronger, faster, heavier, cooler, bigger, meaner, tougher as I play. And I want my enemies to get stronger, faster, heavier, cooler, bigger, meaner, tougher, and die in bloodier, more fantastic ways.
Anyhow, my opinion on current gamestate. I get it, it's alpha, and there's a ton of content missing, but this is the time and place for opinions.
