A decent game but some problems weigh it down a bit for me
The character creation is the best in role playing games, it lets you decide sheppard's first name, gender, class and his apperance. Any shepard you create (male or female) will look great and really belivable.
The graphics in mass effect are stunning. Character models look revolutionary and the enviroments of every planet and space ship look differant and original.
The combat is sort of like gears of war, where you take cover and shoot at the enemy. Depending on what class you pick you might be able to use powers that throw an enemy or overheat their wepons. Combat can be frustrating where you die and go back to a point and have to do everything again. Squad comands are poor so you will probably end up not using them.
Talking to other characters is really fun on Mass effect because shepards responces can be hilarious. You will meet plenty of interesting characters to join your squad. Some have romance side plots and at the end of one of those plots shepard and his lover go to bed together.
Some of Mass effect's bad points are really long loading times (in an elivator especially), un-user friendly quest log and buy interface, combat system (at times) and it may crash a few times on your 360.
Overall Mass effect is a good game (not great) and is worth checking out.
