Sonic Lost Worlds vs Sonic Boom: Shattered Crystals

What are the differences in each? Which is longer? Which has more replay value? I saw that Sonic Lost Worlds has a vs mode. Is that fun? Besides, Sonic Racers, are any other Sonic games planned to come out soon?

Thanks

3ds game vs a wiiU game?

well lost worlds is much prettier.....the little item gimmicks are bit awkward. i was also upset its a mix of 3d and 2d....i would have liked it all in 3D.

i have shattered crystals on 3ds but havnt opened it.

i say lost worlds is better.

lost worlds is also on 3ds

sonic has been dead since 06

Colors and Generations were great. But other than that you're right.

I haven't played either, but I find this site useful for helping me figure out how long a game might be: http://howlongtobeat.com/

Sonic Lost Worlds is more like Super Mario 3D World. Sonic Boom, is like the older style 3D Sonic games but was not accepted. Fans didnt enjoy it too much and complained. Sonic Lost Worlds has a small cult following saying its a great game. Im not sure on replayability, im guessing time trail would help with replayability, but that might be it.

i think sonic boom on wii u is more like sonic adventures, but not on the 3ds.
