Sonic unleashed wii. Good level 3d level design design and when played with a pro controller it's truly a fast paced and fun experience. Colors is far too much 2D and levels beyond act 1 are mostly fluff.
Arguably though Sonic Colors is the more focused and refined game since it's focused on one kind of gameplay and builds on the introduction of boost from Unleashed (before it became an increasingly obvious crutch). Round 1: Art Design Sonic Unleashed and Sonic Colors have a very similar looking style, but how they go about expressing it is literally worlds apart. Sonic Unleashed art design focused on taking real world locales such as China, Italy, Greece, and New York, and transforming them to fit with in the relam of Sonic.
Sonic Unleashed and Sonic Colors are mainline Sonic games released 2 years apart, and have been compared since they came out. Unleashed received a lot of bac. Yeah sonic colours for access reasons you can only play it on wii as opposed to sonic unleashed where it is backwards compatible on xbox one and has a decent sonic generations mod on pc.
Although a remaster isn't really needed just a port. Never played colors, but I beat Unleashed about a week or so ago. It's a rather difficult experience but it's an amazing game with great story, characterization, gameplay, graphics, etc.
Definitely recommend. The quality of the day stages in Unleashed blows Generations' Act 2 stages out the water and the design of Sonic stages in Forces is absolutely awful in terms of atmosphere, design and length. Unleashed has better highs with lower lows while Colors is more consistent in comparison IMO Unleashed does a better job of selling its fantasy of free running around the world at Mach speeds cause of the graphics and the more obstacle course based level design.
For Sonic Colors on the Wii, a GameFAQs message board topic titled "Unleashed vs colors". Sonic Unleashed had the best Day/Normal Sonic levels I've seen in a 3D Sonic game for a while, but the Night Stages are incredibly slow compared to the fast and lively Day stages and the combat is hard to grasp. Sonic Colors didn't have a certain werehog but didn't have the decency to localise the title for us 'Colour' speakers.
