I have not played more than about 25 hrs of skyrim, level 15, but already I can see that I am going to get far fewer perks than I initially thought. At one per level, it's seems that one gets too few benefits out of the perk tree in a play through. From what I've seen on these forums, most players get chars up to level 55-60, after which, for many reasons, the game becomes less interesting and they start again with a new one.

The typical char will get ~60 perks, then, maybe less. That is less than a quarter of the available perks. I realize that this is intentional, to make replay more attractive and limit the redundantly god-like abilities you can attain, but I suggest that increasing the # of perks slightly would improve the experience of not only first, but also subsequent chars. Two perks per level would only get you 120, still less than half the tree. Or maybe something more like one per level, but two extras every third level. Although I enjoy the decision making challenges of the current system, I keep thinking that 29 perks by the time I hit level 30 will seem slim. Especially given the number of perks that have incremental increases.

Just a thought.

Even if I play on master difficulties with enchance high level gameplay mod. The game still quite easy. I haven't tried more perk per level but I think the number of perks is enough to make a good character as long as you are not doing jack of all trade that spread your skills on too many stuff

My advice: Invest points in magic. You will never get bored.
