why cant i use them? please tell me!
A number of reasons.
1. You didn't even have the decency to tell me specifically: what sprites in specific, why you wanted them, what you wanted them for, or anything else along those lines that might be useful to me. I can only assume based on some of your other posts and threads that you wanted my Fakemon for some form of hack.
2. I don't like giving permission for my sprites out. Too many people ask, but for the few times I've said "yes" in the past, nothing comes of it. I'm not a fan of attaching my name to even more uncompleted projects. I also don't like getting my hopes up that some use will come of it.
3. People ask for my sprites, but I don't know why. If your looking to use them for a hack or something, I'm curious why people ask me. I have no back sprites and won't be making back sprites for a long time. Pokemon sprites are useless without those, and if you aren't able to make your own sprites (hence why you're probably asking someone else for some) then what good do my sprites do you? If you know someone who can make the back sprites, then why do you need my front sprites? It doesn't make sense to me. If you can't even realize that, I hardly expect the hack you plan to use them in will get far.
4. You grammar and way with words implies someone who isn't serious. A serious person who really wanted to recruit me for a project would try to set it up to a deal. Would try and convince me to help them. They would spell things out properly, explain everything, and tell me why I should. They wouldn't act so casual about it. You can't even bother to properly tell me much and haven't bothered to even capitalize your own words. A show of disorganization and lack of seriousness. How am I to believe you will take my sprites and make magic with them, when you can't even ask to properly?
So overall, it's because clearly you can't be trusted to represent them properly. I'm picky, stingy, paranoid, selfish, mean, arrogant, and plain just don't trust letting just anyone use my sprites. You made a bad first impression, failed to make any attempt to sell me on it, and your follow up question has come off as whining more than anything else.
I do hope that answers your question adequately.
