2) Populous The Promised Lands 1989, Harpoon Battleset 1989 Their Finest Missions 1989
Correct me if I'm wrong, but aren't those mission packs that don't change anything in the original games?
Well they add missions for the original locations in the case of TFM, new pilots(horse armor) and new missions (akin to 'quests') and Harpoon got new weapons systems and a database update for the original game in addition to an entirely new area of battle(which would put it in several categories). Unkillable is mostly correct, but there were notable changes to platform performance in original scenarios as a result of updated statistics. Sure it would make it a glorified patch, but there it is. New scenarios were also with Populous, but the tilesets were also added to the original game free play mode so they count. Again this addon could be in several categories.
Oh and what do you count cover disks as? Populous the Final Frontier was an addon released with a magazine in 1989 and it could be counted as FREE dlc as a separate campaign as it offered a single new area with 500 levels. So it could be under (3). Depends on whether you count buying the magazine as paying for the addon, or whether the fact that any other thing could have been on the cover or nothing at all and the price would have been the same could technically make it 'FREE'.
