1.I love charcters that when fighting, have ability to not only wield all kinds of weapons, but can certainly manipulate angles of attack from above. Although foot action is somewhat limited, this game does a great job of maneuvering camera and player 360 degrees. Personally, the best fighter for me had to be the PC Prince of Persia middle games that could attack from every possible angle and included significantly manipulating environment and kick attacks. It would be great to see the character have more sophistication in attack mode.
2.Cut scenes vs chosing dialogue. I think there should be more balance in having more, not less cut scenes in "telling the story". IMO, it gets too complicated creating too many storylines that really are still going to have to lead towards a main story. Asssassin's Creed has a great connectedness between some choices but continuing to do story development.
3. Elevate the game more. Climbing should be more than trudging up mountains. Rooftop action is really really fun and creates fabulous views.
4.Horseback riding- not only should it be a method of movement, but obviously attacking can be simply coolness. It's well done on Assassin's Creed II
I haven't got to any kind of flying parts yet, but roleplay games that have balance in story, some connectedness to history along with fantasy, good physical play of character, and some decent choices keep my interest.
If one really wants to have a dramatic diversion in roleplaying though, I'd like to see one where there is a clear changing of the entire lines of outcome. All of them still usually finish with you defeating the evil force. How about one where you have the choice to actually become the evil force and then you're battling the entire game/Kingdom for survival. Raise the controversy level up where you literally are chosing good or evil in final outcome of your character.
