I only played two so far, being Sonic Colors and then Sonic Lost World, both earlier this year for the first time. I found Colors to be super tedious und annoying while Lost World felt fantastic and amazed me with the level design, so that's an easy win for me. I'll be playing Sonic Boom next, somewhere down the line.
My biggest hope is that Sonic Frontiers will be an actual good game and stop making people criticise every tiny little detail. I can't stand all this bitching and crying from the so called fans anymore.
