In arcanum playing a technologist is actually the strongest way to play it, but by far the most demanding.
The core problem with playing technologist is that you need to know for what you're going from day 1, you can't simply dabble in it all.
Also the followers you pick-up is of MUCh higher imporance, virgil(your main follower) won't put it, you need jana stiles, and charisma becomes obsollete, seing as dog+2 followers is MORE then enough followers (magnus+styles, or styles+that poison gnome is the best solutions).
For instance going into herbology is often pointless for technologists, not bcus its not good, but because its not good enough, 1 of the best guns in the game is the tesla-gun, which is also a problem in the game when you first start playing, how the fuck are you supposed to know this?
Tesla gun=you need the gunmaking skill+electricity maxed, from there you want gnades, bcus nades are fucking awesome, but you dont want to waste skillpoints on leveling up your thrown (which is rly counter-intuitive)
Also youl need to get to the anti-magic technology, but thats a spoiler so i wont explain anything about that.
The problem about technologist in arcanum, is you dont get enough information, and its a much less intuitive class to form for urself.
Whilst a fighter-mage just need some strength buff, some dex buff, and the harm spell+combat skill, easypeazy, and you wouldnt need much research to find that this would be a good path.
