I love games. But keep them out of pre-built ROMs and kitchens, please. Why?
1) I, and others, are picky about games and we're not going to like at least one of them. Some people don't want games at all. You're never going to please everyone even if you include them.
2) Waste of space. Either it takes longer to download or upload the ROM/kitchen, or it wastes space on the device.
3) OEM'ing anything into \Windows\ can decrease performance. FormerPalmOS, a much wiser individual than myself, once explained that increasing the file count in the \Windows\ directory decreases performance. Something about it generating some sort of 'catalog list' that has to be read each time you access a system file. I probably just botched his explanation up really bad, but the point remains that extra files should be avoided.
4) Wastes Chef time. They have better things to do than grab game OEMs and make sure they work.
Really, just start collecting CABs on your SD card and add them in with UC or Sashami as you get them, then every ROM you flash will essentially come with games
