Jade Empire was my second BioWare game (KOTOR being the first, of course), and I haven't been able to ignore any of their RPGs since.
I'd got KOTOR2 first (Obsidian rather than Bioware of course) and it didn't really grab me. Back then though, I played Shooter and Flight sims more than RPGs though.
About a year after ME1 came out on the X-Box, one of my mates recommended it as he'd been playing it one of his mates. Got the PC version and got hooked. Since then, I've got a little more hooked on RPGs though Bioware ones seem to be my favourites.
