Just because it's not easy, doesn't mean it can't or shouldn't be done.

They can do random encounters right.

That said, I will say this. I in no way want them to up the system requirements for this game. If random encounters were to put a strain on the game, for some reason, I would not want them to include them.

As much as I think they would improve the game, it is more intelligent to keep system requirements where they are so more people can play the game.

But, come on. Don't tell me it's too hard to create random encounters and not worth it. It makes the world feel alive. It surprises players and adds the element of danger instead of, "Well, I cleared out the world. I'm 100% safe now. I know there's an angry camp of goblins in a temple 100 feet from me, but I'm safe here in Moonhaven. Spiders below? No worries. Undead? Nah. Not worried."
