Starrowind would be great fun... But then, if we just had one relatively tiny island again, there'd be outcry. The developers would have to make literally dozens of planets to satisfy the Star Wars fan lust... And the game's development would take about 20 years. It's nice to dream, anyway.
The game defenitely needs to be longer than the first... I recently replayed Baldur's Gate 2 for about my 20th time (no joke)... And I am still finding new stuff to do! I always rant on about BG2, but that's what kotor 2/3 needs to be like. BG2 in star wars.
