I'm not a fan of short intros where reviewers bluntly tell you to avoid a particular game. There are many different factors for why a title can end up so bad that you want to chug battery acid instead of playing it. Sometimes things don't come together as expected or a team lacks experience, which makes being overly harsh a pointless endeavor. Reviews should serve as a way to give feedback instead of venting your frustrations on the world.
That being said, Turok: Escape from Lost Valley is likely to end up the worst game I review in my career as a critic. For all intents and purposes, avoid this at all costs. It is not worth the frustration it takes to see the ending for yourself. You're better off assuming the video game series ended in 2008 with that stupid rebooted game by Propaganda Games.
If you must learn why I'm saying this, though, read on.
