I've always been trying to keep object count low, even though my game is going to be for PC.
But then, I was following an old tutorial on procedural generation, and it had a little over 12,000 objects! I thought maybe since that was construct classic that it was different, but I quickly created a similar set up in my existing RPG type of game which has over 1,000 events, and it still played fine with 10,000 objects at 60fps and under 15 cpu usage. There were only 3 heroes on screen and 2 enemies, and this is turn based so there's only so much going on at once.
Anyway, the point is how big of deal is object count really? Especially on PC games. My computer is decent, so I don't want to get carried away and find out that it runs like crap on anything less. Of course, I could always test on my old laptop.
