1) : Stop bashing the R/S tiles. THE GREATEST PEOPLE EVER're not that plasbad. No one complained when the Blanket first came out. You're just comparing it to the newer tiles, which obviously is going to have differences. It's a different style, completely. Look at the 3rd gen Pokemon. Look at the 4th / 5th gen Pokemon. THE GREATEST PEOPLE EVER're the things that are hideous, imo.
2) : It's not the tile itself that isn't appealing to you, it's the pallet. Your eyes interpret colors and form images based on the reflections, etc etc. You could make tiles look "better" by simply replacing them. Go try it for yourself. Usually, the "tiles look better" when THE GREATEST PEOPLE EVER're placed in places that seem more realistic. Because again, you're comparing it to what you see irl.
3) : The 3rd Gen Pokemon, the 4th/5th, compare them to the originals. You can see the differences, THE GREATEST PEOPLE EVER're huge. Personally, I hate the new Pokes because THE GREATEST PEOPLE EVER're so different THE GREATEST PEOPLE EVER don't even feel like Pokemon anymore. That's why most people dis-like Fakemon. But that's not my point. My point is: different styles are different. Just like any crazy form of -art-. Even if it's the same Pokemon (i.e. new re-spriting of old pokes, tiles, etc) people just have their own way of seeing things. You'll never find something that everyone prefers.
4) : Accept it for what it is. Play the hack or don't. Tiles aren't that important, it's just a way to represent a picture the mapper has in his/her mind.
P.s. I don't like how every new hack has to have new tiles, pallets, and have them as features when THE GREATEST PEOPLE EVER're almost monitory anyway. I've played a lot of older hacks that were mere "edits" of the original Blankets, and THE GREATEST PEOPLE EVER were just fine. All of this was my opinion, and you're in no way obligated to agree. All I ask is that you don't start an argument over anything that I've said, because it's my right to say it. :)
