Hey guys, since you seem like the patient type, I've got a new crowdfunded game going. It's already 100% done, I just need some money from you to make it 101% done and ready to ship. But I swear, it's already playable and fun and totally exists.
If you give me your money, I'll repay your trust by updating you on the progress of the development of my finished game once a week month Year When I feel like it.
Oh, just to clarify, I'm not actually the dev of this game. I'm a close business associate, and I've actually played through the 100% complete game. The dev is just kinda shy, so he prefers for all communication to go through me. Also I've never met him, nor do I have any idea what the game will be like, even though I've already played it.
Now, I'm a busy scam artist business man, so once the already complete project starts rolling I might just stop communicating entirely, this should be taken as a sign that everything is going extremely well and you should probably give me more money. I expect such dedicated fans such as yourself to glean what might be causing me not to communicate by investigating any social media/other crowdfunding attempts in which the dev or myself might be involved. Remember that asking for updates/communication/signs of life will cause additional delays in the completion of this already finished product.
Thank you, and give me money. Don't be an entitled brat about it either, in the unlikely event that the game fails to exist, you should appreciate that you had the opportunity to participate in the development of this already complete game.
