OVA (Second Edition) is an anime-focused RPG, but that really means you can play anything with it. The second edition improves upon the presentation and content from the first edition, but either is recommended.
The system is d6 based and involves assigning dice to a set of traits and weaknesses. The list of these provided by the game hits most things gamers care about, but it is easy to tweak it as required by the tone, power-level, and setting in question (and the game shows you how). Players roll dice based on their traits and weaknesses and then keep the highest value rolled (doubles, triples, etc. are added together into a single value).
It plays super fast and the combat options makes for some cool strategic choices when choosing your combat stance each round. Players and GM can create tailored attacks and defenses based on base traits and tweaks that give characters more options in battle as well.
The look of the game is amazing. Clay Gardner wrote and laid-out the product and it features the art of Niko Geyer. This is like Anime-styled Nirvana. Every image is gorgeous and builds on the cadre of sample characters used as examples in the game text.
I have GMed and played OVA in both editions and it is fun, fast, and handled a variety of genres and settings without breaking a sweat.
