Hi, I'm new here so I don't know if this has been talked about in depth before but meh, I'm gonna talk about it anyway.
I've not finished my first play through yet (still have korriban to do) but I have found it quite easy. I chose to play a sentinel (now a watchman) and its still been quite straight-forward. Given what I've read about the other classes I know I've picked the 'weakest' class for combat/force, yet still I've perhaps only been challenged once.
Ok so lets cut to it. Lets make the game hard. I did the same thing with KOTOR so I'm gonna list some challenges.
1) Solo it, aside from parts where you are forced to take a party
2) The no equipment (other than armour), stims, shields, upgrades playthrough
3) No force, lightsabers playthrough (not sure how feasable this is)
4) All of the above? (w00t)
I'd like to refine the ideas a bit so lets hear your thoughts!
