Re: Kitty evolution
An RPG has a character or group of characters that you control and usually, create, as they progress through a fictional storyline. Throughout the game, you gradually power up the skills, stats, and equipment of your characters as the enemies get progressively tougher, eventually culminating in a boss battle. Thus, Pokemon is certainly an RPG, as you level up and evolve your monsters to prepare for tougher trainers and, eventually, the Elite Four. Halo, however, is not an RPG, as your pre-defined character's skills remain constant throughout the game. Mario games are not RPGs for the same reason.
Therefore, the topic of this shirt is firmly in the realm of this derby.
