I know a lot of people that level up their ammo or boosters and then forget about skill points for a while. Next thing they know, they have 11 unspent skill points! What's the most unspent skill points you've ever had? And was it on purpose to make the game harder or did you just forget?
Only ever been about 5 or 6 for me. Mostly due to the fact I know what I want to spend it on before I even earn it.
