Otogi 2 is unbeliveibly cool, even without infinate jumps of Suetake (a magical tree, yes a
tree), you can still get very high up via mana-fueled dash uppercuts. And the amount of destruction owns. also the weapons don't need to be reparied anymore
Surprisingly, only 3 monsters return from the original, the Yasha Ravens, the thingys that resemble Doom's lost souls and the huge Centipede boss.
If you've not picked it up yet, search the bargin bins, and play it.
Last thing: They ****ed up Serious Sam 2. The life system in the 1st as more deathmatchy, you just get back up and continue fighting. SS2 chucks you pack to the last checkpoint and 90% of the time resets the monsters.
