Jorev: In RPGs where skills and attributes need to be raised to improve your abilities you will usually want to raise them as quickly as possible if you are a min maxer.
This sort of gameplay can be made interesting, where figuring out the best way to raise skills and attributes ends up being part of the challenge.
For example, in Dragon Quest 1, the ultimate armor is guarded by a powerful monster. Getting it would make leveling up a lot safer and easier, but if you try to get it too early, you will likely die and waste time. The sword is in the final dungeon, and going there at a low level involves a lot of luck, and hoping that you won't fail to run away at a bad time.
I could also mention Disgaea here.
Or, incremental games like Cookie Clicker (and the others I mentioned earlier) have a lot of this going on.
For someone who loves math, this sort of gameplay I actually do find to be quite engaging and challenging.
