Grinding can be fun. Depends on a lot of things. Is grinding to boring (always the same) or interesting (you have to use different tactics, have to take risks). Secondly it should be of low necessicity to progress main story, but other elements like secrets, side quests or achievements could depend on grinding. So you can enjoy the main story if you don't have much time, but have goals to achieve if you like the game so much you wanna sink more time in it. And another thing is, that grinding can be much more fun, if the game gives you ways to do it. For instance a lot of small quests (something like Skyrim for instance) or events that give you incentive to get out and kill a monster you killed hundrreds of times before.
