Mass Effect is a game that shouldn't be missed by anyone.
In the beginning you can customize Commander Shepard however you like, you can even be female. There are a lot of positives about this game. Unlike in most games you already start out as the one in charge you command the team and another awesome thing is you have infinite ammo, all your guns can overheat but they don't take long before you can use them again. You have the option to be good or bad, and the game is all about dialog choice and everything you pick changes how things will turn out in the end. You can always bring two people along with you on the missions telling them where to go and what to do can get a little annoying but nothing major a couple of times Ashley got stuck and I had to reload but it didn't happen often. There are a lot of awesome guns in the game and powers that come handy in tight situations. The game is very long and there are tons of side quests I didn't even finish them all. There are two dlc packs "Bring Down the Sky" and "Pinnacle Station" I didn't play either of these but people have said Bring Down the Sky is the better of the two.
Overall Mass Effect is an amazing game and should be played by every gamer if your a fan of RPG's or not.
