Then have your archer start tossing spells.
You get 80 perks....more than enough to try various skills and abilities.
And like oc2pus said...you only have like 4 or 5 years to try things out before TES VI
Well, if I try to turn my lv40+ archer into a mage, then he won't be a proper mage. Not RPG-wise, and not roleplay wise. Besides, after that point, leveling without abusing the trainer exploits is painfully slow. It's not really worth it.
I prefer to set out with a plan on what class I like to end up playing. The only time I went and just got anything I felt like taking at the moment was my first character, a Nort swordspell, that eventually ended being a dual sword and heavy-armor warrior. It didn't really work out for me. So, I tried almost every possible build with various characters, from destro mage and thief/assasin to monk. I eventually ended up with what I liked best - sniper. But, at that point, I had grown tired of the same quests and dungeons all over again. The fact that the script in Skyrim is below average in most cases doesn't help. The dungeons are all very similar too - once you've been in a couple draugr tombs, you'll never really find anything interesting in another one... dwemer ruins are all similar too, just full of the same traps and annoying spiders, and you know that when you get deeper there are always choruses and falmer... and the bandit outposts - damn, many of them are even complete, shameless copypaste...
They are all very intereting at first... but after about 100-150 or so hours, I've pretty much run out things to do in the world. I've tried just roaming around searching for new stuff and dungeons - yeah, I had fun killing giants and destroying hidden bandit camps, but in all honesty the only thing that kept me playing was trying out new builds. That's what I mainly like in RPGs - all the fiddling with skills and numbers. And I was lucky I had console commands to allow me to skip things like the first dungeon, to jumb straight to lv81 to see how end-game content is (btw, awful - you run around one-shoting everything, then the crappy leveling system allows 1 single arrow to 1-shot you through your dragon armor...). I played a bit more, then got bored even more, and since I had run out of builds, I just uninstalled.
Currently waiting for the CK and DLC, to see if I can make it work that time... gonna building a Black Reaper-style necromancer and go at it again, and hope it works... though I don't see how it could keep me entertained for more than a month more tbh...
BTW was always lv15 by the time I left Riverwood in my latest playthroughs... thanks for Faendel ^^
