This is a really good and I think sadly under played and discussed game. It was very popular in the mid 1990s on release but it seems like it was immediately forgotten about once Starcraft arrived. It's unfortunate because yes it's a simpler and more straight forward game, and not as balanced, but it is very fun and pure.
Warcraft 1 is maybe too slow paced and basic to be enjoyable, but Warcraft 2 remains very playable, as many of the usability of features core to modern RTS games developed here. There are a few things missing, but that just means you have to be more on the ball with the micro.
The map editor was revolutionary at the time, and it was trivially easy to be making usable maps within minutes.
One thing that was delightful about this game was how the community discovered that Farms made for better walls than the actual walls, and so an enormous variety of strategies developed around this. As players developed knowledge of how units were pushed out of buildings, walling off buildings to push units past forest was another strategy that developed from this, creating the potential for sneaky tricks.
One unfortunate thing about the game was that during the original battlenet edition they added a new extra fast speed, which everyone moved to, but that speed actually kinda broke the game in that it became entirely possible to accidentally put your townhall too close to the mine, and your peons would be impossible to remove from mining. So in actuality the second to fastest speed is the correct speed for this game.
I hope this got fixed in the remaster but I heard it was a pretty basic art refresh...
