I definitely prefer slower leveling so that I can really feel the impact of leveling up. If you like that, though, games that have more frequent smaller level increments generally work fine — just save up your skill points or whatever to use them all in batches. I have arguments about this often with a friend I play borderlands with — she likes to use her skill points etc immediately, and when see sees I have a number of them not being used she accuses me of being lazy and forgetting to level up. No, I just want to feel it when I do!
