S0L from Sumo digital presented a challenge over SEGA forums for potential DLC characters in Sonic & All-Stars Racing Transformed of your choice, the challenge is if they could bring a list of three characters that over 1000 people want each he'll send the results for SEGA and they will decide wither they go for it or no, here's his post:
I'll set you a challenge. Without any policing from the SUMO or SEGA crew, if you can all agree on three characters by the 1st of December and prove there is sufficient interest of at least 1000 unique people *per* character, I will present the result to SEGA. I can't promise anything will happen as a result, but since you're starting it...
Let's see if you can organise yourselves in the next few weeks to pull that off!
My sole hints, first you probably need to define some rules, then agree on who will police them, and then run it fairly (no cheating) and deliver something professional and credible I'd be able to use. You are on your own for the rest
--- S0L ---
-Up to three (3) characters may be presented to S0L. -Each character must meet a requirement of interest from one thousand (1000) unique people. In other words, a minimum of 1000 votes must be placed for the character to qualify. -There is no limit to which characters you would like to vote on, but only one vote is allowed per character. -Alternate and/or duplicated votes are strictly discouraged. Suspicions from S0L may void the character(s)'s entry altogether. -The deadline for the movement is marked on December 1st.
Since you can only vote for 3 characters I voted for Axel Stone, Arle Nadja and Vectorman, sorry guys but a man gotta do what he's gotta do, the deadline is December 1st so make an account and sign in, vote for your favorite 3 characters in the list!
