@ marcin: The problem only happens at you, for me they can be installed and played too. For example : asphalt 5 runs extremely smooth.
Otherwise, 7.2.0 works very smooth and stable, I could say that it's way better then 7.1.0
If you do a wipe data/factory reset before and after installation, you'll probably have no problem with the rom.
For all beginners and new guys around, it is strongly advised to stricktly follow the installation guide to avoid any problems while/after installing a rom!
Bricking and malfunctioning can be easily avoided with attention.
Using SEARCH and ADVANCED SEARCH will help you solving your problem. Reading the threads will help you too.
