Williams Arcade's Greatest Hits on Super Nintendo is possibly the best video game compilation ever released
It has 5 of the best arcade games ever released, and all of the games in the collection are shockingly faithful to the arcade machines
the settings are more customizable than I remember them being in the arcade service menus as well, you can augment the difficulty however you like. Freedom that most other games wouldn't give you unless you had a game genie
And for several years this was probably the only format in which highly accurate renditions of these games were easily available in the home. This is especially true of Sinistar, which to my knowledge never had a faithful home release before this collection, and still hasn't ever since then.
Not to mention the few but noticeable improvements that have been made in each game. Sinistar now has the option to minimize the mini map, which gives you more screen space, which is especially useful since Sinistar moves so fast that you need as wide of a field of view as you can get.
It is so good that even in this modern age where I have access to MAME and roms ripped directly from original hardware, this collection is still my preferred way to play all of these games, given both their accuracy and all the quality of life improvements
if you have a SNES you should pick this game up however you can, it really is a masterclass in the practice of game compilation.
