Hello ^^ I've started an RP with Ryu, Xoph, Burpy, and a few others and I'd love to have you on board too! It's a semi-dystopian, Pokémobian (sonic OCs, but with pokemon species) RP, but it has a little bit of a twist with half of the characters that think is a pretty neat idea, so if any of that sounds interesting, read the TL;DR version in this blog and check it out further if you'd be interested.
On the whole, I think it's good. Mac's snarky attitude and general overractiveness carries it a lot, and Scarlet's an interesting character, especially considering it looked a lot like "Mac would beat up the gang and take a shine to Scarlet" at the start. However, there's a few things I'd like to point out:
There's a few cases (albeit not many) of telling, not showing. Stories are more interesting if characters are shown to be something, instead of being told it. For example, saying someone is a badass is not as good as showing them decimate a gang of thugs, and (in the case of SR), saying a bartender was a noob isn't as good as showing them accidentally spilling over glasses and forgetting orders.
The only thing about the plot that really irks me is how a Chaos Emerald ended up in a jewellery store without anyone noticing? I'd understand if it was Pre-Super Genesis Wave (because Chaos Emeralds are everywhere) but not in this context.
I'm planning on making a pre-SR fanfic to show more instead of just having the reader guess. Also... maybe the Emerald was a fake, used to see if criminals knew what they were doing before catching them?
