I tried Dino D-Day way back in May, and again in July, and both times I got bored of it quite quickly. I just didn't care enough for its rather lackluster gameplay. Though recently, I noticed they've been adding new stuff to it, compies and whatnot.
Maybe sometime in the near future I'll try it again. Might see something I missed last time.
Former former... former... former... yeah, you get the idea.
