For me, something that will always grab my attention and get me motivated to work on a game is if the story interests me. I know that sounds weird coming from a programming engineer, but it's a lot of what got me into games in the first place. After that, if the overall environment and gameplay are engaging, that will also pull me in. This is just the brief summary, but I guess the short answer is the genre of a game doesn't matter to me so much as the story, environment, and gameplay do
