War of the Dead is very similar to Zelda II, but I never played more than 2 seconds of it. Very high difficulty and language barrier, with some glitches.
Blood Gear is also pretty similar to Zelda II, but a lot better. So is Wonder Boy III (Dragon's Curse)
Honestly, I enjoyed Neutopia II a lot more than Neutopia. Not as innovative as LTTP, but it is more "fun" and overall less tedious in my opinion.
