I don't know. Depends on the game. Some games I can be into grinding. Others not so much. RPG's I tend to not mind so much since it comes with the territory of leveling up and growing stronger.
But for something like Tony Hawk 1 and 2 where you have a grind to level 100 trophy attached and it involves slow dished out XP that requires you to grind at least 100 hours of Multiplayer then I say fuck that. I want no part of that.
Just depends on the game.
No pun intended?
I agree with Dan; all depends on the game.
Let's take the Working Designs-translated games for the Sega CD:
- Lunar: The Silver Star
- Lunar: Eternal Blue
- Vay
LSS: A normal RPG where you need to grind between each town, but not excessively-so. It becomes a casual experience and is all part of the fun; this is a type of grind I like. Other examples would be Phantasy Star III, Lunar Walking School, Albert Odyssey: The Legend of Aldeann and Evolution: The World of Sacred Device.
LEB: The same as above, but now you have hidden/secret/special areas/side quests, where you can grind for extra stuff/levels, in order to deal with the really tough parts (in hindsight, I should've grinded a lot more for the final boss battles than I did, but oh well) and the epilogue. This is extra grinding, but it falls under the, "self-imposed challenge," or, "extra content," category; this is a type of grind I LOVE. Other examples would be Phantasy Star IV, Skies of Arcadia, Grandia II and Evolution II: Far Off Promise.
Vay: Also a normal and straight-forward RPG, but with few extras (none, actually) and you have to grind a minimum of an hour or so (or more), between each town, otherwise you will be soundly-trounced: you don't have lucky battles (in your favour) or critical hits; you will get killed and killed swiftly, unless you grind an absolute shit-ton more than you're comfortable with; this is the type of grind I LOATHE and gets on my nerves to death. Other examples would be Phantasy Star II. I must say, I really enjoyed Vay though (gave it an 8/10), as it is very-memorable, has a kick-ass soundtrack and an interesting plot.
If it is a non-RPG, as Dan mentioned above, I don't really care how long I have to play it, to beat it. Achievements though, are an entirely-different beast.
