[quote name='A Happy Panda']Mmm...just picked up the second to last Collector's Edition at the Beaverton, OR Best Buy...
Only put in about 15 hours into the first ME before the terrible Mako sections, tons of technical glitches and bugs and not-very-good shooting gameplay basically made me say "mmmm nope"
Hopefully its better...still on the fence on opening it though.[/QUOTE]
The Mako sections are removed, but they have been replaced with this planet scanning mini game that is pretty much required for you to play if you ever want to purchase upgrades. Personally I would rather drive around in the Mako, but you might feel different.
I have played for around 7 hours and I have only had one glitch which resulted in me being stuck on some terrain and unable to move after I used the charge ability. That is on the PC version though.
The shooting gameplay is much improved, but at a cost. Almost all RPG mechanics have been taken out of the game. Also you cannot use any weapons that you are not trained for. In other words if you play an Adept the only weapons you can use are Pistols, SMGs and Heavy Weapons. Unlike in ME1 where you could use any weapon, but you would suck with it if you didn't have training.
