I used Professor Layton and was impressed. There is an underwater cave entrance that is pretty cool. I haven't done a whole lot on it so I may try some of these.
-1035240907947293046 is an extreme seed, it has many strange and wonderful mountains, ravines, huge caves and a large stronghold.
Chiyogami is a nice balanced seed with a bit of everything on it, both seeds are 1.8 compatible.
