Didn't sleep for 2 days. It's been a while since a game did that to me.
(+) Fighting: is good. Use cover, sidekick can fight. Big battles are a challenge and give good pleasure for knocking off the local hub, or finally taking over the opposition's compound.
(+) Strategy: is great. OK, at least addictive. It's not rocket science but having options for how to take over a joint is sweeeeet.
(+) Pressure System: totally rocks. Being intimidating, knocking them around, all the different ways to persuade the owner to give you the keys to the establishment is, well, really fun!
(-) Graphics etc is fine. Certainly not great, but they don't need to be. With any interesting game (Morrowind is good example here) really we just fill in the details.
So... Check your bargin bin, pay that 5 dollars, and get a totally great deal!
