By the way, weird to see Lost World in the 5th round while Pumpkin Adventure isn't there. Had a bad opponent, I guess 
. Hmm let's take a peek in the previous round...
WHAT!!! PUMPKIN ADVENTURE 3 ACTUALLY *LOST* TO VAMPIRE KILLER???
/me kills on everyone who voted for Vampire Killer.
The game sucks! It suffers from terrible slowdowns, and it just a so-so platformer, games like Akin, Contra, Psycho World or Fantasm Soldier would beat it any day, and I personally like Lupin III a lot more too. And then there is Pumpkin Adventure III, one of the coolest RPG's for MSX, and it actually *loses*??? I can't believe it! It's probably because PA3 is a Dutch amateur product, which most people outside of the Netherlands probably don't know? Anyways, grr, 'best MSX2 game'?? Pah!
