Man the first game pissed me off so bad. I tried so hard to get into it. I loved the soundtrack and graphic quality. It ran smooth as butter and looked great. Loved the attention to detail on the dinos.
HOWEVER... the lack of an immediate Sandbox mode was annoying as I tried getting through the single player missions and kept getting stuck. The damn point where Dinos are breaking out all over the place from the fences had me pulling my hair out. It was like a nonstop occurrence. Even after learning that if you mix them with the gene that causes them to be more aggressive, I took that gene out of the pool. Yet they continued to break out. I said, "F" this. It was so annoying to constantly have to tranquilize, transport, repair, rinse and repeat.
I hope they rework some of the annoying aspects in the sequel.
