Trying to squeeze as much text as possible while keeping it readable is a challenge. What are your favourite fonts for this? 

I'll go first with Roboto Condensed (a classic) and BenchNine

I usually like to use Roboto more often. It's one of my favorite fonts. But I try to use others too. First time seeing the BenchNine font. Maybe I'll try incorporating it into some of my newer games. 

Korolev Condensed

I used Anantason ExtraCondensed Thin for my entry.

Whoops, I didn't use a condensed font for my own bookmark game though. But it was all good, had to use some kernings :P
