Just loved the whole trilogy, how choices from each part influence the story and characters' developments in later parts.
I made three or four separate playthroughs of the whole trilogy for every romance combination I liked.
Being an ammo hoarder I avoided any shooting builds in all sequels (Andromeda too)
The game mechanic bonuses from playing through with different classes made replays more fun.
Luckily some people uploaded all the elevator and vehicle and cockpit talk combinations to youtube =)
