My Ideas on K3:
1. Plantes involved: Coruscant or Corellia, 1 planet from K2 possibly Telos or Nar Shardaa, A new Space Station concept, at least 1 planet we've heard of but haven't seen before, 1 planet we've seen in games from other genres, 1 planet we've never heard of, 1 planet from the films transitioned to the game and 1 planet from the first game possibly Rakatan world or Manaan.
2. Timeline: 2 years after K2 events.
3. Plot: Rebuilding of the Jedi Order.
4. Plot: Rebuilding the Jedi Order. Jedi Exile from K2 is the Main Villain. ( Here's how. The canonical story for K2 could be bad. Exile defeats the sith lords and takes the throne of the Korriban sith empire although player has choice whether or not Atris was spared. Carth helps hide Bastila from the rest of the sith. Bastila redeems Atris if spared. Together with Atris or alone with Carth, Bastila Finds a Force Sensitive teenager, possibly 14 yrs old[Main PC]. The Player gets to, not only make choices that effect everyone, but the player also gets to shape his character physically as he grows older. Species choice should also be an option even if it's a choice between only 5 species[Humans included] as well as Joining Jedi/sith order or not being a Jedi at all [Other prestige classes available such as Bounty Hunter]. Somewhere in the middle of the Story, Revan should Return. Not fully a beast like he should turn out to be, but only leveled up to a certain point. Maybe since his "search for the true sith" wasn't as eventful as he had thought, he hadn't been able to really keep his skills and use of the force honed. Player's character makeup from previous 2 games should determine outcome of characters' abilities in this game. Gender and Appearance for both though, should be pre-determined by Game designers. When Revan returns he becomes a PC. He should also be the Head of the Jedi order at that time if and when it is Re-established.
5. Characters: Main character, Bastila, Carth, Hk-47, T3-M4, Revan, Bao-dur[player finds out that Bao-dur abandoned the "General" when he fell to the darkside], Brianna [see "Bao-dur"], Zaalbar [After he finds out about Revan's return he joins the squad and renews his life-debt], Mission [Cameo], Disciple [Cameo], Atris [Choice], Two new characters possibly force sensitives picked up along the way that player can train into Jedi, and 1 or 2 characters that are based upon choice of Gender or Alignment.
6. Villains: Exile, Atton [trained as a Dark Jedi, Player has a choice of either saving him or killing him], Visas Marr [see "Atton"], Hanharr [Hunting Main party with some sith soldiers for the Exile], Goto [ the real goto, not the droid], Two Huge new characters possibly one sith as Exile's peer, partner or apprentice, and the other as a Elite fighter such as a Echani specialist, Bounty Hunter or Genohardan Leader.
7. Ships: Ebon Hawk, [Player should have a choice from a list of ships as to which type of ship they want, recommended: not all freighters] Some Unique ships identified with certain characters, such as the Exiles ship.
8. Vehicles: There should also be more at least one battle involving huge vehicles. One aspect of StarWars that everybody loves is the large scale planetary battles.
9.Organizations: Jedi [Duh], Republic army, the Sith [should have more of a downscaled presence compared to the other two, just a little bit], Genohardan [The way K1 set up this organization and it's secrecy along with it being a "driving force of the Galaxy" is perfect for making them a Major if not the Major Obstacle in The Heroes way], The exchange [definitly downscale this one. we don't want it to get worn out for a possible K4 and K5 appearance], Czerka and a Competitor of Czerka, possibly a pre-rendering of one of the CIS corporations.
10. Overall: Make it Starwars! I loved Both games, but the one thing K1 has over K2, is it felt like you were making your own starwars movie. K2 just felt like you were playin a game. And Definitly have a randomize enemy respawn system like K1, not level limit like K2. More Drama and way more Space Action, possibly assaulting a Capital ship or something[space fighting and boarding].
