That’s fair, it is very highly praised. I definitely recommend playing them in order as choices you make in each game affect the future titles too. ME2 is the most popular, I personally like the first one the best but I get that it’s not everyone’s cup of tea, at least compared to its sequel, but if you’re playing through the first one and find it a bit lacking or a touch boring I’d recommend pushing through anyway because CD 2 and 3 will probably be more enjoyable for you, and you really do need to play them in order imo. Otherwise it’s kind of like watching Empire Strikes Back without first watching A New Hope.

As for remastered vs original, I actually haven’t played the remastered before, only the originals (which I’ve played many times), but I’ve read it’s a good remaster so it’s probably safe to go with it.
