1) I have to disagree on the skill system. While ME2's model was made far better in ME3, I have to say that I prefer the more subtly incremental system of the original Mass Effect. This is a matter of taste, though, I admit.SajuukKhar said:Yes there was a noticeable difference between Mass Effect and Mass Effect 2
Mass effect 2 had
-A far better skill system
-Shooter mechanics that worked instead of the "I can stand in one spot and never die" mechanics ME1 had.
-A cover system that WORKED
-Considerably less repetitive, and far more detailed, locations
amongst other things
The real sin of the ME2 system was that non-combat class skills were ripped out of the game altogether, which took away the the whole balance of Non-Combat Utility VS Combat Strength for classes.
2+3) Shooting mechanics were improved, yes. This was a good thing. However, the ridiculous focus on (and poor implementation of) the Gears-style cover system made combat in the game very repetitive. This, again, was largely fixed in Mass Effect 3, where the cover system and environments were redesigned to encourage more forward momentum during combat.
Another issue, later fixed in ME3, was that the usefulness of the franchise's signature Biotics was reduced to an absurdly low level. They went from overpowered in ME1 to mostly useless on difficulties above Normal in ME2. ME3 finally struck a nice balance by reworking the health/armor/shield/barrier mechanics.
4) Less repetitive locations, yes. But also less numerous, and instead we got planet scanning... which is infinitely more repetitive than locating resources on the planets in ME1.
