Using PoG as an example, there are practical limits to attributes.
Strength - I have taken the hero up to 2500 at which point he can take out any NPC including the Guardian in one blow with no weapon.
Vitality - The higher you go, the more health points you garner on each level up.
Dexterity - Luck - Marksmanship - All seem to have little effect if taken above 120 - 150.
Speed - Game plays well at about 13 - 14 and is really hard to control at 17. If you increase speed to 200 - 300 you can walk through walls, trees, etc. (Actually, "walk" is probably not the right word, "charge" would be more accurate.) Before teleportation spells were available I used this method to explore areas of the maps which were blocked off.
Undead and Mind protection - A strange thing happens if you take these above 100. The hero gains health when he gets hit rather than loses it.

My Doctor said I was having too much wine, women, and song - so I gave up singing because 2 out of 3 is not so bad.
