both where awsome games but as cleric said 2 was very rushed and unfinished
1 took lets see 4 years to make and complete 2 came out roughly a year MAYBE 2 if your very kucky after 1.
Obsidian utterly ruined the story imo, infact there where areas that where IN the game, nar shadaa i believe where the area was made etc infact was supposed to add to the story of what happened to revan if you came back with HK47. but because they where so rushed decided to put a permanentely locked door infront of it and said mecht thatl do. didnt even decide to delete the area from the map.
but yes gameplay alot more to it, such as armour and skills, story whys- the exile was a wussy compared to revan hehehe
