I actually prefer a format Andromeda is going with way more than the OT's (especially ME2 and ME3) heavily streamlined experience. (OT - original trilogy)
Those games were very linear, to the point where you could tell there is a fight coming, just by the sheer amount of covers scattered around the room, there was never a surprise, you saw crates/blocks/rocks, you knew you're gonna fight. ME2 had barely any RPG left in it, with like... 4 abilities with 4 ranks per character? I think that's how it was. ME3 improved on that, but still not enough.
Andromeda seems to have much more to it, much more things to do, more things to manage, more of everything, really, crafting, gathering shit and these vaults that sound like some MMO dungeon are especially interesting. Aaand it's in the Mass Effect universe, so I like it already.
I'm not saying the linear nature of OT was bad, it wasn't, great characters, great universe created and fascinating story made up for all of that. I'm just saying that I'll happily try something different, with not much worse story at that I'll bet, or even better one, who knows.
What I like the most about Andromeda's story is that it seems to be much more... personal, find us a new home and all that. OT was so epic, pompous and high stakes with its "save the
world galaxy" premise that it basically used all of that up, again, not a bad thing, I just want something different this time around.
I'm happy that it won't be a trilogy (allegedly) and I won't be hung up on a cliffhanger, just get a nice neat ending and I'll feel complete... until the next game comes out.
