Your probably sick of these but I think you need a little more insight.
1. Waudby is lying in your thread. Thats because he is afraid and stupid. He stole your tiles. He claims idea stealing exists (hahahahahahaha good one). Hes annoying. Get over that.
2. Your idea of stealing and spriting needs to be reassessed. Let's cut the bull here, making your own sprites by reference of DP images is still a DP image. Nintendo has copyright on all the sprites, its not like the this here. Nintendo doesn't have copyright over the looks and the double letters ii cause that would be absurd. You might get away with it sure but its in the same position as Waudby. If you say that its yours when its someone elses its not really fair. Also you claim editing the sprite is still stealing, dont we all do that in the forum, you just happen to be a victim of it. Just because we cant see nintendo doesnt mean that they exist.
3. I was going to comment on placeholders but i reread and you didnt call a placeholder stealing (yet) so I wont bring up an issue on that.
4. So what should you realize? You are a victim like nintendo. Someone stole "your" tiles. Basically since you are already doing something illegal you have to realize that WHAT YOU PRESENT OR SHOW CAN BE USED. Does it matter if its legal, nope. Cant reiterate enough about how the game showcase takes the copyrighted pokemon sprites. You can only try to diminish the chance and use of the tiles you do not want to publish. There are many examples and you can ask me for some about how to diminish this chance. In terms of this forum I think they should crank up the number of moderators so they can check theft (its not supported by PC sure but another forum can support it).
So am I a goody goody two shoes that follows the rules. HELL NAH. lol. I am creating a pokemon game right now with the sprites (i dont use your sprites because it is a special type of game). Neo-Dragon does it, waudby does it, boodasack does it, almost everyone on the forum does it. But they have to accept the fact that they are susceptible to the same things as you. Accept it or dont. I hope you keep up your game I am a big fan of your project (its one of the few i think will make it to the finish). PM me if you have any questions are concerns.
