When I was younger I had a full copy of Star Craft 1 and the Brood War Expansion for the PC unopened and I was looking for something I didn't already play yet as a teenager.
I usually don't like Strategy games and I was never good at them, so at first I would use cheats to complete the story instead of grind through the entire game, and getting my butt kicked by the computer. After all I had no prior experience with strategy games before I played this one.
After I found out how to play I stopped using cheats, and played the game normally in which is surprisingly fun and the story is great if you follow the story,
it's like opening a good book, it has such a great story, that after I kept playing the 6 campaigns over and over again I created my own after math of the Brood War Campaigns a few times, using my own sound, programming triggers and my own custom levels. Using the Campaign editor in which came with all physical copies of the PC version of Star Craft 1.
