How so?
I really don't want to go around and bring a dead horse from the dead, but here is a link to Zack0Wack0's profile where if you see his last post was that VCE is obsolete, and its easy to see why.
The amount of exploits that bad users used it for, "controlling" players via impulse pushes, stuff like that ruined it, but aside from that he said it was not as good as he wanted and basically he said its a stuffty alternative for people who don't know how to script properly.
Someone is already working on a new variable event system, it will not be compatible with old vce events.
This really isn't the best topic for this. Just use the search button if you want to know why its obsolete, I don't really feel like looking up every single issue it had.
