When you were young, you liked this game. Now that you're old... you still like this game.
Gameplay: Getting to run around, collecting rings, and beating up robots and the boss, Robotnik after 3 Acts in each of the 6 Zones.
Awesome: Sonic is still the fastest thing alive! (well I guess...), almost a Mario copy cat, difficulty is fair enough.
Bummer: Getting dizzy from bonus rounds, easy achievements, sometimes glitchy.
Control: Still plays the same as the classic, plays as a 2D platformer... because it is one.
Awesome: Easy controls
Bummer: Stupid camera when looking up and down.
Sound: Same sounds as the original.
Awesome: Fun sound effects, not realistic but who cares.
Bummer: Sometimes cluttered sound, I hate the sound of adding up your score after each act. But the last do-do-ding is cool.
Graphics: Colorful
Awesome: Still the same as before, awesome option of the "smoother" which takes away the pixelness and makes it completely smooth
Bummer: Eh... just that it's retro. Doesn't bother me.
Overall: Great choice to come back to! I recommend it since it's only 400 Microsoft Points! And yes, it's easy for even grandparents to play. Go for it!
