Ireally enjoyed Elite like Tomo, but havent seen it in years, and also enjoyed Civ. Another great "space" game came out some years later, had Mark Hammel in the cut scenes, but the name i forget right now
Computer games are fun, and easy because there are no rules really and no set up. Thet usually have some level of solitaire ability.
But most commercial computer games are fairly shallow and regulalry get things somewhat or (more usually) a lot wrong.
