On a side note, if you think NHL '94 is unrealistically quiet, I invite you to come up here and watch a high level hockey game. The crowds are usually so quiet you can hear conversations between the referee and players. If anything, EA actually has the proper crowd noise volume in comparison to the hockey games I attend live.
NHL 94 on the SNES blew me away when it first came out. I had a TV with a built in VHS recorder (remember those?) and I used to tape some of my games and watch them later. I was so obsessed with the game that I convinced myself that the different position players actually looked different from one another. Who can forget their first time checking an opposing player into the bench? I remember mastering the one timers long before I could aim my shots and score on every breakaway. I didn't even try to play the Genesis version until after I'd mastered the SNES version (about 6 months later). To me, the SNES version was always superior. Everybody kept saying how the Genesis version was "faster", but I could never see it myself. I also loved the graphics and better colors on the SNES version, which is why I'll always see it as clearly better than the Genesis version. I'd give it an A+. It's easily my favorite sports titles of all time, and maybe only behind the original Contra and Metal Gear Solid for favorite game of all time.
When I went from 60fps playing Grand Prix Challenge on the PS2 back to Nascar 06 running at 30fps on the PS2, I clearly noticed the difference. NASCAR felt considerably slower That's the same kind of difference I see between the SNES and Genesis version. It is true that you get used to the slower speed as the game action starts flowing you don't notice as much but its there.
The SNES makes better use of the extra buttons for the game but overall the Genesis version is easily superior in my eyes.
