auroraparadox: Thanks for pointing out the guide. I followed it and it the game looks great. I just finished the training and started a new game.
Do you have any recommendations as to what I should train in?
What I usually do to start is to upgrade Computers, Electronics, and Lockpicking. Computers allows you to hack terminals, which removes the need to ever find passwords if you don't feel like searching. Electronics and Lockpicking at Trained will take 25% off of a keypad or locked door with one multitool/lockpick. For all three, that's all you really need for the whole game, although if the game universe captures your fancy, you might want to upgrade Computers to Advanced to give you more time to read emails.
Honestly, there's no wrong way to build your character, but I will say that the skills that see the least use are probably Environmental Training and Swimming.
One note with Computers: You can hack ATMs too, and the higher the level of your Computer skill, the more money you can steal. Additionally, once you log out of a hacked ATM, it will be out of service, and you can't try to log in if you find an account and PIN.
