>>13558282I can only find one reason (which I can't even confirm, as I do not have anything from the eShop..)
The pokemon games from the beginning were all about connectivity and the ability to trade and battle with other people whom also had the games, but I don't think it is possible with the virtual console games (no link cable, etc)
These games are still great games, but the inability to capture all of the pokemon in the games without the ability to trade leaves them kind of incomplete. I don't think Nintendo would go through the trouble of working out these issues as remakes have already been made within the past 10 years. and are compatible with current versions of the games.
