I've checked the list at the top but not gone through the thread. Sorry if any duplicates.

Modern Fantasy (is this the same as low fantasy?) 
Modern Science Fiction (could be covered by 'Soft Sci Fi', though I'm not familiar with that term) 
Harry Potter
Abstract (doesn't really fit into other categories, GM thinks it's somehow weird)
Experimental
Period (as in, set in a given time-period and roughly sticking to it)
TBC (for party size)
Player-driven
GM-driven
Under Construction/Ideas Please (the GM has a core concept, but wants more player input than usual in building it)
High Casual (go ooooooon ;))
