I think it was Street Fighter Collection on Saturn. (Not Street Fighter Anniversary Collection on PS2 or Street Fighter 30th Anniversary Collection on PS4, Steam)
Decades back, I wanted a good home port of Super Street Fighter 2 Turbo ever since it was released in the arcades. I waited for an SNES release but to no avail. It got released to 3d0 but I wasn't willing to pay for one since it was so expensive and SSF2T was the only game I wanted on it...not worth the money.
Then Street Fighter Alpha came for PS1 came out which I bought and enjoyed but I still wanted ST. Then Street Fighter Alpha 2 came out for Saturn which I also bought. Street Fighter the Movie came out which interested me since it had had most of Super Turbo's characters and gameplay but it wasn't really Super SF2 Turbo...it almost felt like Capcom was taunting me. I also bought Eurocom/Gametek's version for PC but it didn't feel right...it had an amazing recomposed soundtrack though.
Throughout this time, I just played Super Turbo every chance I got in the arcade but still wanting to very much, own it at home.
Finally, they announced Street Fighter Collection for PS1 and Saturn, on systems I already possessed and it was going to have Super SF2 Turbo on it..and made by Capcom themselves. I wanted it so much that I ordered through this Chips and Bits store advertised in one of my old gaming magazines. I didn't know it at the time that while the ad showed an enormous listing of games they supposedly had in their storehouse, I learned later that this store was a scam. Apparently, they had a habit of taking the money and not delivering the game to their customers. Which happened to me...they never delivered the game!!!

(I learned they suffered under a huge lawsuit later and rightfully so but the damage has already been done)
In any case, I finally managed to obtain Street Fighter Collection from relatives who bought the game for me while they were abroad.
When I finally got to own and play SSF2T, something was...off. It was TOO EASY! I played Super Turbo a lot in the arcades throughout all that time and what I wanted was exactly what I experienced there. I'm probably the only one who wants the really difficult AI of Super Turbo (I know there are a ton of complaints about the difficult AI for ST in SF 30th Anniversary and Capcom Classics Collection throughout the Internet but I am not one of them) and the Saturn version even at the highest difficulty seemed brain dead to me. It was doubly disappointing especially since I already got scammed by that dishonest store. The only thing good about it was the inclusion of Street Fighter Alpha 2 Gold but that wasn't why I bought it.
Later on, I finally got the perfect version of Super Turbo that I wanted when I bought Super Street Fighter IIX for Matching Service on Dreamcast (and has Tien Akuma). At some point, emulation came in and that was a welcome surprise as well.
Nowadays, I rarely buy games without feedback from other people...not just official reviews but from people who actually bought the game and played it. I'd also ask questions in public forums about certain aspects about the game I'm interested in which might not have been addressed in official reviews.
