Each game is pretty recognizable if you've played video games since the 1980's so I'm not going to bother naming them just check out the pics!
The ones with white/gray backgrounds are ones I haven't decided on a background color for just yet though feel free to suggest one please. My main goal here is to create a set of ten coasters out of these ten sets, one image from each set. So if you are of the mind to help feel free to pick an image from each set, just put the name and a number next to it. Start the numbering from left to right, top to bottom of the main block of images for each set and if you like the extra one just put "extra" next to the name and a number next to that if there are multiple, thanks!
You may resume your normal life functions now. :)
(I didn't create or rip any of the actual sprites, I just found them on the web and cut them down to the size I wanted. Credit for such things goes to the respective creators and individuals who took the time to make all of them.)
