I know people like to laugh at differing viewpoints but this is how I describe it to people as well. I've played longer than 8 hours, though. I'm 13-14 hours in and I can go to the ending I think, but I'm finishing up Tali's and Garrus' stories.
The gameplay is kinda meh. I'm just going through it to beat the game. In the beginning I was all gears of war-style covering and hitting pistol shots from cover, but then I realized I could just place 2 snipers behind cover while I run around spamming singularity. :lol Gets the job done most of the time. I don't even really use guns anymore except on bosses. One time I was busy running around killing minions and I find out my 2 guys killed the boss already. :|
