All 4 titles in the collection are solid. Sonic 2 and 3 are easy 9/10s (4.5 stars). My rating here is moreso on the merits of the collection, which is good in that it brings us the Taxman versions of the games on consoles. But as far as offering up the definitive editions of all 4 titles, they could have done better. Especially in regards to Sonic 3 & Knuckles.
