hercufles: nice :) uhm i have to start playing spellcasters in games like these strangely i always play melee characters to give up in the end because at the end monsters ect are tough for a melee
As SheBear said, melee characters in Arcanum are actually pretty easy. I played one for my first character, and had no trouble at all, especially later in the game.
Having said that, a pure melee character in Arcanum can actually be rather boring. Nothing's really a challenge in the last third of the game. If you want a melee character, I would recommend trying either some magical skills or some tech skills in addition to fighting. One thing that could be fun would be a technological fighter, and you could learn smithing so you can craft better weapons and armor with your tech skills. This will be a little harder than a pure melee fighter because you won't be able to use the powerful magical weapons (or rather, you won't get their magical effects) but the powerful technological weapons are pretty good too I think. Or you could do a magical fighter, for whom the powerful magical weapons would work even better. You could learn some summoning spells to help out in combat, or buff spells to increase your stats.
I have also heard that playing a pure mage is very easy. I haven't tried it yet. There's also tons of different magic schools so you could probably play five different mage characters with different spells and still have a good time with each of them.
Pure tech characters are considered hardest, but if you are drawn to tech, one of the easiest to play might be a grenadier. Use a boomerang and thrown grenades as your primary weapons and you should do pretty well.
