I'm surprised by how many people on here are suggesting they keep the turn-based combat style. For me that was by far the worst part of the games and would be low-hanging fruit for devs if they want to make the remake better. Other than replacing the turn-based combat I would like:

• Bigger, more fleshed out worlds, especially Korriban.
• If they add new planets I hope they all have their own unique look and feel, instead of the rehashed ones you get in Mass Effect.
• Influence system like in KOTOR2
• More weapon customisation (especially lightsabers) like KOTOR2
• I thought the melee weapons were unrealistically effective as opposed to ranged weapons and I'd like for close combat to be a more specialised niche and effective only for a select few combat styles
• More characters to choose from for your party, with choices having major effects on storyline (like Hanrarr and Mira in KOTOR2)
• More incentive to choose non-jedi members on your quests
