I keep overcomplicating things as I go along.

So, I'm like, "well, I don't really want to put mana guns in my game even though they're technically canon" pun intended, so I'll make them Gates, or, 1-way portals to an event or source of energy in the past. Oh and I could have multiple gates, and they could shoot at the same time like a shmup... but how would I manage them? Or should they shoot separate? This is how complexity creeps in.
