I think the promotion with Nickeledeon is more from SEGA than Gamefam.
Nickeledeon is under Paramount afterall, who worked with SEGA in Sonic 3 movie.
I think it could be a convenience on both accounts. Whenever Gamefam were happening to make a TMNT roblox game at the time, who knows. But the crosspromotional proposal was there.
I know. Also EA killed one of my favorite game franchises, Bookworm.
I still hate them for it.
That looks like a fun game for Countdown fans.
