Just under 9 hours played.. beat the game a couple times, all achievements (not many, which can be good or bad depending on how you feel about them). Probably won't play it again, but you never know. The game is quite enjoyable. The level sizes are decent although unless you're going for achievements you don't really go all over the map in most levels. I never used a controller for this game, as it's far more smooth driving then say Renegade Ops, but I could see it being nice so I leave that to personal preference.
The power-ups and upgrades are definitely cool, as I found out you will probably use most of them a couple times depending on the level. The side missions are a nice touch as well.
The simplicity of this game is great, it's a straight forward game and really easy to pick up. The only flaw I see with this is long term replay value.
7.5/10 due to no long term replay value but very much worth it especially on sale
