For those who are still on the fence about this set because it's G1 cassettes but don't like SG, it was once said that these toys can be used for something other than SG.
There is a custom sticker sheet that comes with the set that gives one the option to give these figures a little more variety and be more like the SG versions, but if one chooses to forgo applying these stickers, that leaves these figures less like their SG character selves and more free to represent non-SG characters.
For Soundwave, don't like SG? No problem! Ta-da! Consider him Evil Decepticon "Sonic White" Soundwave.
For Blaster, don't like SG? Worry no more! A little imagination and boom! He's the Heroic Autobot Blaster's brother Bluster.
For the cassettes, don't like SG? Get this! Now they're additional members to further expand the ranks of you Heroic Autobot and Evil Decepticon cassette armies, ripe for the creative renaming of whatever names you please.
