To quote something I just posted in a private message to someone enquiring about the game:

It gives me strong Deus Ex feelings. To whit:
Hey! The PC port is half the price of the console version at launch!
Hey! It's meant to be a good PC port!
Hey! The game's supposed to be good!
Hey! This intro is quite good!
Hey! This is quite a striking game, visually!
Hey! It hard-locked my PC!
It's by the same publisher. Square-Enix. I'm still waiting for them to patch my copy of Deus Ex into playable form. I checked various forums before purchasing and no one reported tech problems. After the crash I checked the steam forums. It was full of people complaining about the same issue. Now I recall why I started checking the steam forums before purchasing a PC game! This is the first time in ages that I neglected to do so.

I picked it up because it sounded like Yakuza's world plus Assassins Creed's mobility by way of Arkham Asylum's combat and a story which, based on some spoilers, might be intriguing. There's a side-order of Just Cause 2 served with it. It's supposed to be quite easy, and if you don't fancy following the plot there's a good bit of side material to indulge in. It sounded like a good game to unwind with after a long day at work.

For the record, I loathed GTA4. Every single thing about it. The only good Rockstar game IMO is Bully, and that still has some big problems.

Now to see if I can get it working ...
