I see. It appears I didn't get the whole message then. So what you're saying is

higher level -> you get more points & skills cost more points -> what's the point?!

Correct? Still the system kinda works, because a high level doesn't mean all equipped skills are equal in level, so some of them cost more, some less, the system allows for investing in multiple lower skills. That's the whole reason I think. So the value of points are indeed changing, by some linear or logarithmic formula, they're high in value for lower skills and low for higher skills. Has anyone ever made a comparision of a skill tree system and the one described above? I'd like to read one.

It's been a while since I played the alpha (twice so far). What strikes me is the way skills are at both 'discrete levels' and 'continuous' ones. Am I right to assume that strenght, constitution, agility, ... are continuous and 'fire magic', 'reason', 'luck', ... are discrete (the ones you were talking about)? It's funny. It's strange. It's fine by me.
I'm not making any comments though ... no time and lots of other players posting on this forum. Am I still babbling? Let me finish my work.
