Hell yeah. This game was alright, but the soundtrack was so good I accidentally platinumed it. Also those random ass ikaruga segments were so much fun.
Frontiers was honestly the biggest disappointment I had with a 3D Sonic game since '06 (I thankfully didn't play Rise of Lyric despite owning a Wii U.)
Making an open world zone Sonic game is all well and good, but the world just feels so lifeless. Not to mention that the mini-stages are literally regurgitated from other 3D Boost era Sonic games.
