Alright combat, good story (maybe not so 3) and world building. Wish there was more morally gray options not just good vs bad or that the Paragon options actually have a negative effect just to mix it up vs like it always being the correct choice 100% of the time.
Combat is total shit 1. Best in 2. Alright 3.
Story is best 1. good 2. just alright 3 (dialog is fine just main overarching plot).
