They're both pretty similar, I guess - and developed at the same company (although by totally different people).
Another World starts with the bloke getting transported into 'another world' during a malfunction at a particle accelerator. The first level includes that black monster you mention chasing him around, before he gets captured by some aliens.
Flashback begins with some guy escaping a spaceship on a hover-bike thing, and getting shot down. The first level is in a jungle with little droids and stuff.
In answer to this topic... I'd kill for someone to remake Exile for the DS.
