Mediev and Starry Ice are correct.

The Jedi mind powers will lead to more dialog options. It will also allow you to make an NPC do something that they might not want to "Give me your money." or "You do not want to fight me" kind of things.

It does work in conjunction with Persuade. You are able to influence people without Jedi mind powers. Sometimes you can just convince them that they should tell you the info you want or let you get away without paying. But by adding the Mind Power to your persuade skill you get a much better chance of getting them to obey you. And, as I just said, there may be more dialog options for Mind Affected NPCs.

That is a good question that I don't think has been asked before. Well done.

The answer is, you do not need to identify items. I know usually in DnD/RPG type games, like our Neverwinter Nights game, you do have to have a store keeper or Mage or whatever identify special items for you. But we chose not to bother with that malarky. We figured that if you're a Jedi, you should be able to tell what sort of gun it is or be able to ask someone who'd know, like Carth. So we just chose not to botehr with identifying.

There are some story and plot issues that I cannot discuss that may or may not come into play. But aside from that there are memory restrictions that come into play.

For each PC you need a set on animations to make them walk, fight, talk, whatever. The more different types of body, the more space taken up in memory just to make them work. I imagine that we could have made alien PCs but it would have meant less human heads to choose from, less combat animations, possibly a poorer frame rate. We chose to give the player many choices for their human instead.

In general, if you wish to avoid an enemy by using stealth, you will be able to.

Now it might be possible that the enemy is guarding a door (or whatever) that you need to go through, you would have to go back and fight him. But usually, if you choose to avoid an opponent, you can.

Yep. You can place mines and then get the enemy to chase you over them.

But remember, your enemies can do the same thing.

You (and your party members) cannot trip your own mines. And enemies do not trip their own mines.

There may be a way to detect the mines. There is a skill called Awareness. The higher your awareness, the more likely you will notice hidden things, like mines. So if you have a PC or a party NPC with a high Awareness skill you will see, what I will call, "the mine effect" that shows you where they are. Different mines have different effects, like poison, fragmentation, flash (stun), etc. If you detect them, you will know what sort they are.

Pretty much waht you said. Credits, items, unique items, plot items, that type of thing. You cannot earn extra Force Powers by completing quests (except that you will get extra XP and with extra XP you will level up faster and if you level up you may get Force Powers).
