MUST READ...BEST RPG SEQUEL EVER (Pros and Cons)
The first Mass Effect was mediocre . I played ME halfway then went right into ME2, it's too tempting ^^ For people that doesn't like RPG games, but you think you might give this game a try, then most likely you might not get enough sleep for a few weeks....If you played the prequel, this game is definitely an improvement in every corner you can think of. This game is different from other RPG's, even with other Bioware games like DOA, you get a different experience, and of course a better one. Overall, this game is slightly underrated, but definitely give a try.
Pros:
Best RPG Graphics to date
Perfect Story with different amazing environments
Best RPG Voice Acting to date
Great character design with beautiful looks
Multiple replay value(Male & Female,6 classes with 6 other specialization classes and upgrades with different weapons)
Great sound design
Cheaper to buy for PC version and better compared to 360
Cons:
Extra boring planets to explore(some people won't like them)
Very few boring missions
occasional graphical glitches that got me stuck so I had to restart from last checkpoint
Update April 2012: This game is arguably better than ME3.
