Thank you Bioware for one of the best role playing trilogys of all time *(No spoilers)*

User Rating: 9.5 | Mass Effect 3 X360
I have played ME, ME2 and of course ME3.
ME: 10
ME2: 10
ME3: 9.5

Good:
Combat has improoved. You can import your character from ME2. Graphics are awsome. Story line is very impressive, it sucks you in and doesn't let go. A lot of fun of exploring space, planets and playing side missions. Bigger choise in number of weapons. I am happy to see that there is a way to customisie armour and at Citadel you can buy non customisable armour if you like. Paragon and renegade system. Everything was absolutely perfect, till the ending of the game...

Bad:
I hate the ending! Despite I am ME fan. Ending looks very cheap and poorly executed. On ME1 or ME2 you could've had a lot of squad members, but on ME3 you can only have 6. Because of this a couldn't give a perfect 10.

All in all, if you played previous series it is a must play, despite the ending of course.
