The Swords of Ditto - a by the books 'hero vs reincarnation of evil story' that experimented with permadeath, where if you die evil reigns until the hero is reincarnated and chosen to go fight the evil again. and it had EVERYTHING in its favor. an amazing art style, Devolver acting as the publisher, local co-op, promises of every hero you control having a different adventure. but in the end it was just so limited to what could actually be done, and it was repetitive and grindy as hell. if done right it could have been amazing, worth 100-hour save files just to explore everything, hidden secrets that only the most dedicated players could discover. but it just wasnt...

Spore - if Spore was made correctly, it would still have a dedicated fanbase today fight me on this. and the thing is that they werent even far off from making something great. Spore is still a competently made game that I have personally sunk hundred of hours into, but if there was just more content to be seen it would have blown all these new-age space sims (No Mans Sky, Star Citizen, etc) out of the water. make creature creation more intuitive, have more stuff to do in the space stage to help expand your empire, make the tribal stage less boring, add more strategy to the civ stage, and make the creature stage more diverse. the foundation is there, it just only has about 25% of what it would have
