Sonic Generations (PC)
I have played until City Escape, a Sonic Adventure 2 level. Up until this point, I have also gathered all the Red Rings, which means that I have even gotten the more frustrating sections. One of Modern's Red Rings is at such a spot as to leave little room of error, making it rather frustrating to get. I am talking about the first Red Ring that requires jumping on a ramp to reach a high place, followed by another ramp to touch the Red Ring. That was so frustrating also because that section also forces you to go forward, so it's impossible to do it again without restarting the level. Even Sonic Lost World's Red Rings aren't as frustrating as this, since that game at least have smarter placement of checkpoints.
Anyway, I wanted to play the game as the Super Mario Generations mod, but I had problems with that so had to settle for playing the original, which is a pity because I really wanted to play the Friend Challenges with Mario characters. Too bad there are no Youtube videos with Friend Challenges using the Mario mod, except Donkey Kong in Modern Rooftop Run.
Thank you for reading.
