D:OS is certainly not the pinnacle of game design so far, but I really disagree with the sentiment that it is 'unsatisfying'. I've finished the alpha several times over, and I had fun every time. I enjoy finding new equipment, improving my stats and generally building my character in this game. It was satisying to come back to the lighthouse boss and beating him after getting my ass kicked the first time. It sounds like a very basic thing, but it's rare in games nowadays.
I think you can definitely criticize the mechanics from a theoretical and technical point of view, and I'm not an expert on the matter, but for me the game passes the important litmus test of being fun in a visceral sense. I definitely get that itch if I haven't played in a while.
I also fought the lighthouse boss twice. First time I ran when I realized he would continue to rez the wolves. Lucky to have that "teleport to town" button!
Well I'm happy for you, but I'm the opposite as far as character building goes. I don't really like anything about it--
-I don't like buying skills from merchants
-I dislike having a single stat point at each level up
-I very much dislike the random "every 3rd level you get a talent point and sometimes every 2nd level if we feel like it, but on level 5 you don't get a stat point, and if it's a thursday you don't get a stat point but you get 1 talent point and 1 ability point" ridiculousness
-I'm annoyed at how talents are basically an extra stat point. Just give more stat points and get rid of talents if you aren't going to make them different.
Because there are so few points gained each level, it feels pointless to level up at all - aside from having 'enough' HP for the next encounter. Whoopee. One point feels like next to no change. It all feels VERY unsatisfying to me.
