Well as someone who is going to be using a lot of the RTP I can confirm that for a small project going too deeply into custom assets isn't really something that can feasibly be done. Even a well meaning project needs to decide where to spend the money .. And most will decide to spend it on cg/character art/sprite edits. However even I who will be using the rtp HEAVILY think that games like last heroes are a bit .. lazy. It's about selling something with it's own unique feel to it. Also let's face it because rpgmaker is easy to use there are going to be lots of bad games. I hope mine rises above this but I am new. And the workload is extreme to say the least. I spend at least 5/6 hours a day in front of my computer working on the game. Between doing simple rtp recolors/tweaks, Networking with artists and developing the game. I have something put by for development of the game. But I also need to eat so I need to do my own freelance work. I really have my hands full as a solo dev. And the kind of money I would need to spend to bankroll custom tiles for my game is still beyond me despite years of saving. It would pretty much eat up all my development funds at once. All in all I'd rather have cool character art, Sprite art and CG thanks. The rtp tiles are good enough.
