Query: These are considered gems..?

I gave this disc a rental and was extremely disappointed with the content. The six game gear titles are an automatic waste of space, and Sonic: R and Sonic the Fighters are decent for archival value but don't really hold anything that will keep players coming back for more. Sonic CD is actually quite fun, but time travel function aside it's not terribly different from the early Sonic games which can be found on the Sonic Mega Collection. You can unlock the old Vectorman games as well, and they do add a bit more value to this package.If you're looking for classic 2D Sonic gaming, the Mega Collection is the compilation to check out. Hardcore fans will like what Sonic Gems has to offer, but the content is too dated and shallow to recommend to anyone else.
