IGN: Sonic the Hedgehog 4 is born from the wants of the series' biggest fans. Taking SEGA's mascot back to his 2D roots, it's an attempt to break out of the cycle of hope and despair that's accompanied nearly every game with the blue hedgehog over the past decade. There are no sidekicks, no questionable inter-species relationships and no mindless hub worlds. It's just all the things that made you fall in love with the series in the early nineties, repackaged and refined for this generation of consoles.

Two-day event includes exclusive reveals, trailers and playable games on show floor.

CEO Haruki Satomi said Sega will "take these lessons into account for future initiatives"

Rovio “found it difficult to advance its initially planned business development,” says Sega.
