This is a sampling of Sonic games as scored by Backloggd. Backloggd is like Metacritic in that it lets people submit a score (0.5-5.0) and lists the average of those scores, but Backloggd has a lot more people submitting scores, giving a bigger sample size than Metacritic. This isn't to like, "objectively" prove if X Sonic game is good or bad or whatever, I just like looking at data, and maybe it'd spark interesting discussion. THE CREAM OF THE CROP Sonic 3K - 4.2 Sonic Mania - 4.0 THE GOODIES Adventure 2 Battle - 3.8 Generations - 3.8 Sonic 2 (16-bit) - 3.7 The Murder of Sonic the Hedgehog - 3.7 Frontiers - 3.6 Colors (Wii) - 3.5 Adventure - 3.5 NOT QUITE AS GOODIES CD - 3.4 Unleashed (PS3/360) - 3.3 Unleashed (Wii/PS2) - 3.1 Sonic 1 (16-bit) - 3.1 Sonic Heroes - 3.0 BAD Lost World (Wii U) - 2.5 Shadow the Hedgehog - 2.4 3D Blast - 2.3 4 Episode 2 - 2.3 THE TIER WITH SONIC 06 Forces - 1.9 06 - 1.8 4 Episode 1 - 1.6 FANGAMES FOR FUN Sonic P-06 - 4.0 (the fan remake, not the OG 0.6) Sonic Robo Blast 2 - 4.0 Omens - 1.6 One obvious problem with this is sampling bias. Fangames have less people that play them, so reviews for them tend to be polarized. I can't find any hard statistics on this but it does seem that Backloggd's userbase skews a bit younger, considering how a lot of 8-bit games get middling scores (in general, not just the Sonic ones :P).
