Nintendo made a quality item, probably the biggest complaint is the chosen games for the system or even the fact there is only 21 game and the price, and maybe how short the controller cable is... and no button to get home menu on by default. But it works, easy, simple, and in HD, and while against someone's will, probably gonna be hacked to put other preferred games on it and even scalped to no end.
Besides the last part, is a collectors item and a quality novelty product for family and friends for people 25 years older since it was a deal. Is not a terrible product, but is true there is other options like virtual console with more options for games on wii or wii u (or 3ds if you like portable gaming) and i'm talking legitimate means here, or buying a actual snes or some mock system like retron5, and actual carts, though the carts seem to be higher priced for some demanding lots of money. Either way, is acknowledged is quality work on both is emulation and presentation and hardware, and only people who actually enjoy their childhood would enjoy it with a friend.
Honestly i appreciate compilations, there plenty of games on there, that many probably don't even know about and wouldn't have cared to try, sonic ultimate genesis collection has beyond oasis, I never knew about it but it is a very good game and glad to play it now that it was bundled with other games like, sonic the hedgehog, kid chameleon, streets of rage, dr robotnik mean bean machine, shining force, and phantasy star. Compilations are good thing to some people. Buying one, you may find something you would enjoy, and even if you don't you still have stuff you sure you can enjoy.
