if you dont know cyperpunk 2020 was a fun and challenging game because it never used a traditional leveling system that rpgs are fond of it was done buy skill level with more skill challenges than average
the logic behind this is that if you are a hardcore solo (a mercenary solider ) who has spent years mastering gun combat among others in a straight up fire fight with a gang banger who only got his pistol yesterday
you win because your skill with guns is better
but due to environment and such you can also lose
when a gang banger sneaks up behind a solo no matter what the solos gun skill the gang banger gets a flanking and a surprise attack bonus like in real life situation like how a trained cop or solider can be killed buy untrained fighters
the game cp2020 encourages tactics and skill in cp2020 your more likely to win a fight by knowing and using you environment
in short your skill level only helps luck (in the form of weapon misfires and fumbles) environment (in the form of cover and flanking) can and usually do matter as much as skill level
read the cyberpunk 2020 rule books cause that is apparently the rule set they want to use for 2077 you can find copy's on the net in websites like cyberpunkasia
