My apologies for the delayed response. I essentially removed them as 1) they were no longer selling anyway and 2) I didn't want to confuse audiences with those games and this one (and future projects). I was getting the sense that there was a bit of confusion there now. I will see if there's some way I can try and bundle them all together, but for now I've simply de-listed those first games.
People who purchased the previous games can continue to download them. If you do want a copy of them, please feel free to reach out and we'll see what we can do.
