Well you have to give credit where credit is due. For it's time it was a fantastic fan game. I remember it fondly, and I almost would like to see it redone one of these days, perhaps as a simple level hack of Sonic 3, since that's kind of all it is.
I WAS gonna use it in mine... but considering the overwhelming negative feedback, and the general reactions to this topic... I'm taking it out... some people like it, myself included... but many more people don't, and those that do like it won't give that much of a shit about its absence.
Well, just use mine or one of the subsequent enhancements to the sprite if you're concerned about the public opinion. That way you can both include it and not worry about the consensus.
I think most people use that particular sprite not only because Sonic looks cool in it, but also because it's a sprite of him falling. All of the classic games had him walking/standing in mid-air if he wasn't rolling. This looks kind of strange, and feels almost out-of-character for Sonic, who has been displayed and represented as a character who is very in-control of his body. Just look at how he leaps around in the Sonic CD intro! It only makes sense that Sonic would fall in this graceful/cool manner, rather than flailing his feet around. And, I'd like to note that everyone only mentions this frame's use in Sonic CD for the "I'm outta here" bit, but he also uses it when walking off of the edge, and falling down from the top of the second 3D-ish ramp in Palmtree Panic Act 1.
Really? I've never noticed that. I always seen the game use his walking or spinning sprites when falling off an edge.
As I said, it's only if you walk off of the edge of the second 3D-ish ramp in Palmtree Panic Act 1. It displays as you fall down. It also locks the horizontal controls while you fall. Give it a shot! I've seen it in the PC port, Gems Collection Port, and Taxman port.
I use this sprite in Sonic 2 Secret Rings Control/Edition because it's the best fit for a jump cancel sprite and it doesn't require someone else drawing one for me.
Fan games have been using the same sprites, over and over, since the beginning. The reason why you never see original sprites in fan games is because nobody can or wants to take the time to create them, and if they can, it's usually only for an original project. In this case, this sprite's "pose" is SUPER COOL to anyone because Sonic looks really serious, and he's never posed like this in any other classic game... so everyone wants a piece of that "cool" pie in their fan game. That said, sprite edits are OK, but they never really show any of the true potential a person might have to make something original. On another note, I find that the most enjoyment I get out of any fan game is when they're trying to be their own production with fun, original ideas, and not another copy or sequel of any other official Sonic game.
