They are very old games, but if you are interested, get them while they are permanently free. History has shown that permanently free games can be made unfree(not a real word). Like Dragonsphere. Instead of permanently free, maybe I should say “temporary permanently free for the foreseeable future”. But that is just too long to type.
Anyway, time to make a new tag permafree to separate the permanently available for free games from the available free for a limited time games.
