Probably. It's okay, just poor next to Deus Ex in that yes, RPG elements are watered down, levels are too small (thanks Xbox for that) and overall it just doesn't have quite the same level of awsomeness as Deus Ex.
But... it does have a fair bit of the same Deus Ex DNA in it. It does offer a fun experience. And with Deus Ex 3 apparently on the way - you might just want to see what happens.
I will say the shooting is weak in it though - better to view it as an action thriller rather than a shooter.
I suspect it might look more than a little weak graphically now.
Heck, I'm not really selling it, am I? Well, I bought and played it cheap and thought it was okay despite the flaws.
