Re Hermenegild's post above:
Computer, Electronic and Mechanical skills for the MC, are raised thru the WORK button (3 AP)
Combat and Sex skills, are raised by training bots IN those skills.
Social, is the gigantic PITA, raised by relaxing at the bar. (takes f-o-r-e-v-e-r)
In each case, you are currently able to train a bot in any given skill, to 1 level above your own skill. If it is Combat or Sex, you can continue to train the bot in that skill, and the MC will gain XP until the skill rises to the next, whereupon the Bot starts gaining XP again.
The only real grind I have issue with, is the horrid return on relaxing at the bar. Each day has 4 time periods, 5 AP each. 1 AP to leave and then 4 to RELAX. I have gotten 0 XP from 4 turns of relaxing, and I have gotten 200 XP from 4 turns of relaxing. I have also gotten 0 XP from a full DAY (16 xp spent relaxing and 4 spent leaving the shop) with a high of 332 XP for 1 day of relaxing. Going from C to A in social, takes about a month, of relaxing. which is to say 120 time periods. (or so it seems at any rate. Perhaps I need to actually tally and track that to ascertain the validity of my estimation) Just seems to OFTEN be a + or ++ to mood, with no XP gain.
question for other players:
on the hardest difficulty setting, do you find that your ability to make the payments, is almost 100% dependent upon the very 1st bot oyu manage to salvage? If it's a D bot with any extended needs...you're sunk. If it's a B bot with only a few repairs needed...you're in like Flint. That difficulty setting just seems SO dependent on "the luck of the draw", for your 1st bot find.
