One the slicker and classier TM games out there. Upgrade system is solid, and the levels don't get TOO hard until about halfway through. Two minor complaints: Some of the ingredients' colors are way too similar; folks with minor color-blindness (like me, I guess) make silly mistakes. Also, the game seems to slow down a bit once you're playing for an hour or two. That could just be my decent-not-awesome laptop, though. As far as shelf-life goes, TGCC stacks up pretty well. Those who love collecting upgrades, achievements, and "mastery" scores will probably enjoy the repeat visits. Solid graphics (aside from that minor color gripe), cool little sub-missions, and an overall excellent presentation.
