I don't really care about how big a game is, as long as I'm satisfied with it at the end. I do tend to buy shorter games during sales though, since there are games where the price feels a bit too high for what they have to offer.
One thing I really like about shorter games is that they're usually the ones that I'm more likely to replay. I don't usually replay games but something like Bayonetta is way more enticing to play through again than BotW, for example.
