You can make anything seem pointless with this mindset, what are you trying to say?
I don't understand why having the ability to play as a certain type of character in a TT Game really matters for more than 5 minutes. At the end of the day, at least to me, it's all the same thing. They all move in similar ways, have similar speed, and each character will have at least one special ability that may or may not be shared with other characters.
I don't get how "playing as a dinosaur" is a fun concept in a TT Game. In Turok splitscreen, it was entertaining because it was hunter vs. prey. In a TT Game, I can't really see it being any more than just a simple model change with some abilities tied to the model that you can't access with other characters. The characters are more like tools than they are actual characters or entertaining.
