Do games on the Mac App Store work on Mavericks or would they all need updated?
What? I don't understand where the logic of your question comes from.
They work just fine.
CCleaner on Mountain Lion worked; but no longer works on Mavericks. Have you tried games on Mavericks?

All my games work on Mavericks.
I still don't understand the logic behind your question. Mavericks is not a "new architecture", thus, it supports everything that Mountain Lion was able to handle, plus much more, thanks to the video improvements.
Mavericks is only an optimization to the redundancies of Mountain Lion.
Mavericks can be upgraded from Mountain Lion without doing a clean install with no repercussions, however, an app may not be able to handle that due to their bad coding, which would require you to reinstall the app again. This is not Mavericks' fault, this is the developer's fault.
If you just upgraded to Mavericks, try a reinstall of your apps.
If you did a clean install and your apps don't work, then contact the developer, this is a major issue from their part.
Edit: Why would someone use CCleaner? You do realize that you are not using Windows right? and things such as registry problems only apply to Windows right?
The problem is that you asked a blanket question, most will work but some may need to be updated. Try asking about specific games.
CCLeaner is not just for Registry problems. It cleans out Cache memory and increases performance of all web browsers. I plan to buy a rMBP.
GTA San Andreas. Dirt 2. Minecraft. Cod 4. Grid.
I dont have all those games but I can tell you Minecraft and CoD4 work without any issue. Seeing as GTA and Dirt 2 are both newer than CoD 4 I doubt they would have any trouble either but I havent tested them.
If you owned any of them, could you try them for me?
As I said, I dont own San Andreas or Dirt 2 but Minecraft and CoD4 are both fine.

Will CoD 4 run on the rMBP 13'' with 8Gb of RAM, 2.4Ghz dua core i5 Haswell, 256Gb SSD, integrated Intel Iris?
The system requirements can be found HERE. By the look of it that computer should have absolutely no trouble running CoD4.
I plan to buy the 15" retina with Iris Pro, 2.0Ghz quad core i7 turbo boosted up to 3.2Ghz, 8Gb of DDR3 1600Mhz RAM. Is that better for gaming? Is the iris pro dedicated graphics or integrated?
