Aapo put the old Cataclysm in extras-devel, not sure if latest versions are as clean compile as whales kept the original (one warning only through whole iirc), PRIME (the new ZAPM) stopped compiling on N900 soon after reactivation for example. Brogue, frozen depths (runs with qemu, brogue natively) and Rogue Survivor (win only): are probably my favourites. And adom of course. Btw, I wonder if glshim would allow now to compile dcss in graphical mode. Worked for quite a few games. (I might have a working arm version of AliensRL somewhere btw, never got access to DoomRL's sources, if you're interested could try to dig it up)
