Learning New Skills
This idea has been floating in my mind for some time now...
If you can get new skills from the HHC Eye Augmentations, why wouldn't your char be able to pay some sort of ''Courses'' or other way to learn some Skills? I mean, Eye Surgery already removes your Myopia and gives you Eagle Eye, so why shouldn't you be able to go to some sort of Educational Institution and learn skills like Electrician and Hacking?
Of course, just like the Eye Augmentations's substantial price tag, such tuition services would also be very, very expensive (which isn't too far fetched from how RL is, hahah).
Also, so far, I think that you should only be able to learn minor skills (like Hacking, Electricity, etc.) which won't allow a high-end char to simply learn Strong, Tough and Melee, and become a relentless killing machine (where would be the fun in that? Part of what makes this game so enjoyable is how ''normal'' Philip feels; to the point you can identify yourself with him.).
Plus, given the futuristic Cyberpunk-esque place that the DMC is, all of this ''Learning'' could be just installing a chip in your brain and DLing the info onto it.
So far, I think that the skills available and their prices should go like this:
-Hacking <3000$> (This skill is used very few times and has no impact on Combat. However, all those moments in which you make use of it, it becomes pivotal to surviving, like with the SkyCorps Hooverbike.)
-Electrician <5500$> (Just as with Hacking, this skill is used very times, but it's necessary for end-game stuff like creating the HGR)
-Mechanic <$10000> (This skill comes pretty handy on many situations, like building Vehicles or escaping a ZZ's Deathbot. So, having it can affect a couple things which could upset balance. Hence the price tag)
-Medicine <$25000> (Now this is the big boy! A skill as pivotal as Medicine could really upset the game's balance. Hence, the prize tag; if you survive long enough to save all those grands, then you're already good enough that it won't upset the game's balance)
