[interface stuff trimmed although they look like good suggestions ]
Some questions:
1- Are skill class-related? for example, as a quarterback, I wasn't able to put skill points in pick locks.
2- In my first game, I died because of radiation sickness; what is a way to deal with it? I started drinking potions but this resulted in me having more radiation and being teleported while drunk in a room full of enemies hahaha..
3- I tried to look at a sludge vat, but pressing "." I got no informations; isn't there still a description of it? and what's the use of it?
1. Yes. What skills advance automatically and in which ones can you invest points (and how many) is something that comes with profession. Software engineers suck with light guns, but are pretty good with handguns, for instance. Or, if a character that's not a psion somehow mutates, they won't be able to put skill points in their mutant powers, while psions can add points to any mutant power on levelup. Heavy guns - space marine, lockpicking&swords - ninja, unarmed - astronaut, repair - janitor, etc. Maybe they could do with some tooltips on the selection screen if that's doable.
2. Radiation sickness is one of the biggest dangers. There is a potion that reduces your radiation level (rad-away), an implant that purges radiation over time, a medical procedure that gets rid of your radiation, and some equipment pieces that protect against radiation with varying degrees of safety. Be
very wary of buggy items that might have atomic processes going on inside them. Also, if you manage to mutate into the "restoration" power, you can survive terminal radiation sickness (or poisoning for that matter).
3. Sludge vats have several uses
but I feel that's a bit too spoil-y.
Also, you shouldn't ever throw away the wimpy gun - unless you're way too overencumbered and everything else is much more valuable. Wimpy guns are that, wimpy, but they have a fundamental trait that sets them apart from all other guns. At least that's my advice
