That was one of the issues with the arcade addon - it didn't paginate correctly. And since the devs stopped working on it, it's as good as it's ever going to be.
So "All" isn't really "all", merely "Top 25 games".
As to the others, I'd have to get the core programs back and install them. The Civ Clicker would be easy. The HalSpace Traders not so much. In fact, I did a lot of behind the scenes stuff with that one to randomize and make the universe bigger to prevent the congestion that you find in the original iteration.
I also tried to make a super planet guarded by a massive amount of ships and defense but apparently unless the planet is owned by a player it doesn't fight back against invaders. So what happened was a player found the planet and was like, "Score!!"
