Easily for me. What's the point in levelling if enemies are just harder to defeat? What's the point in doing quests at low levels if you'll be stuck with a weak weapon and never have a challenge? Then again, it's not like there's a point to levelling anyway, so we'll just take the weak weapon and have it stay weak while we stay weak and the enemies stay weak.
I'm sorry, but that's just dumb. The difficulty of playing is NOT a measurement of progression. Ideally, the player should find new challenges all the time.
Which Oblivion's system accomplished beautifully. Oh, and what's the point in levelling? Oh, I duno, how about getting better weapons, better armour, becoming more powerful, being allowed to do many more quests, fighting stronger opponents, dominating NPCs etc. etc. ?
Seriously, there are too many morrowind sympathisers in this forum..
