Since you mentioned the Turbo List, I'm guessing that you got into the Turbo after it was discontinued.
Did the Turbo Mailing List actually exist before the Turbo was discontinued? When I got on it the newest games were Sapphire and Working Love. It was dead in the US, or as good as dead. I guess I really don't know how far back it went, but I was assuming 1994 or so.
As for the OP's question, yeah, big time. My first system was a US Duo. I bought it for CD games so I played CD games.
Eventually I realized that the transition to CD was more than just the medium. To me there are three district periods of PCE games:
1) The Salad Days: mostly action games and many are arcade conversions. Mostly HuCard. There are a lot of really basic games from this period, but also some extraordinary awesome stuff like CRUSH!
2) The Renaissance: The PCE really finds its legs. Dracula X, Tengai 2, Spriggen. Mostly Super CD with a few Hu and ACDs. A huge shift towards sims and RPGs, but still a fair amount of shooters. Not a lot of HuCards.
3) The Otaku Ghetto: An almost total focus on sims and RPGs, mostly sims. Almost no HuCards (far to expensive to manufacture at this point and the few PCE fans all had CDROM2s by now).
So basically, as the system got older, things moved more to CD. This lead to more games that were better suited to doing things with CD that SFC couldn't do with cart (play Emerald Dragon or Flash Hiders on SFC, seriously, they are shadows) but that led away from action. By the time the PCE died it had become...well, its no secret as to why the PC-FX turned out the way it did. It wasn't a good sequel to PCE in 1987, but it was pretty spot on for a sequel to PCE circa 1994. (i.e.: you push I to advance the text...a lot).
So while I appreciate the "multi-media" content of CD games, if I want a quality action game I need to consider HuCards. The entire Soldier series for example, and all the "real" Bombermans are only on HuCard. You absolutely need HuCard, big time, for the entire PCE experience...although I didn't see it when the stuff was new.
