Demonic Blade, things that you can legitimately claim as entirely your own are things that are either made uniquely different or are somewhat difficult to do and have not been done yet. This treasure hunting system is a good example of such a thing, and if you should happen to make it you would most certainly be added to the credits. Things like your transparency system and your leveling system, however, are not such a thing. They are simple things that any knowledgable people can do, if they wanted to add something like that to their game. Just because they do not brag about it and post it everywhere demanding credit (like you seem to be), it does not give you the right to call them stupid or lazy.
Sorry to spam your topic Levent, but this is something that I want Demonic Blade to realize.
