Troika! is Planescape engaged to Monty Python. It's bizarre and soaked in British humor.
It features some pretty interesting mechanics, including character generation that's almost automatic—you roll the dice because it's assumed characters can die easily (though they don't have to).
Initiative is handled by taking a bag and throwing in an item for everyone involved in the fight, plus one extra item marked as the end of the round. You then pull these items out of the bag blindly, and the character whose item is drawn goes next. If the end-of-round item is pulled early, everything goes back in the bag and you start over. It perfectly captures the chaos of battle.

The book includes an example adventure where players must navigate bizarre encounters on a hotel staircase to reach the top floor, where they've rented a room. You can see an example in the photo.

Troika je Planescape zasnoubeny s Monty Pythonem. Je bizarni a prosaknuta britskym smyslem pro humor.
Obsahuje docela zajimave mechanicke reseni, mj se postavy generujou temer automaticky, hodem kostkou, protoze se predpoklada, ze muzou snadno zahynout (ikdyz se to stat nemusi).
Iniciativa se resi tim, ze se vezme sacek, tam se nahazou jakekoliv predmety za kazdeho, kdo bojuje + jeden, ktery se oznaci za konec tahu. Pak se tyto predmety naslepo vytahujou ze sacku a na tahu je ta postava, ci predmet byl zrovna vytazen. Pokud se predcasne vytahne konec tahu, tak se vsechno dava zpatky do sacku a jede se znovu. Melo by to zachytit zmatek, ktery se odehrava behem bitev.

Soucasti knihy je priklad dobrodruzstvi, ktere spociva v tom, ze se musi hraci dostat pres bizarni strety na schodisti hotelu na jeho posledni podlahu, kde maji pronajaty pokoj. Priklad muzete videt na fotce.
