I think it's perfectly acceptable to make a game that takes advantage of more modern hardware. The engine has matured, I'm sorry if your computers haven't matured along with it. That was kind of the whole point of the SCP though, to take advantage of newer hardware. I'm really starting to consider deleting posts that keep complaining about hardware requirements, especially from repeat offenders. The game isn't anywhere near release, so stop worrying that it won't run on your hardware as of now.
Back to the topic, the subsystem limit shouldn't be an issue, in fact this allows us to seemingly control more turrets with fewer subsystems. Firepoints can be dispersed along the trench, instead of grouped, giving it the appearance of up to three turrets per control system just based on there being three firepoints per turret subobject. This actually works to our advantage. The only problem is when people start shooting firepoints and not actual turret control stations, but we can probably take that into account with some creativity as well. This won't matter if the subsystem limit gets bumped, we can do whatever we want, but I'm not counting on that happening anytime soon since I believe that's slated for 3.7.
