We don't have any Tiny Titans, and TTGO were probably published only because it was played on Cartoon Network I own 11 DC books by myself and there were the only ones I could find and most of them are in english, meaning they weren't even published here. In polish I've got... one ugh. (not including 90s Batmans)

I’ve got 3 TTGO!
1 YJ 100 page spectacular thing
1 “special” issue which is basically Raven on LSD
2 CN YJ
I’ve got 16 issues of Tiny Titans XD 
A TT: Outsiders (Secret files and origins) … has a fuckload of pages.
 An issue of Robin I bought only ‘cause the cover was awesome (dead Batman, awww yeaa)
And some hercules thing I never bothered to read properly.
Basically,
All I own is Tiny Titans
‘cause I can’t afford to catch up on anything. 

But that’s okay
‘cause Tiny Titans is fucking amazing
