http://supremestarcraft2.com/alpha.php found this post of what starcraft looked 2 and up from when it was released.
Its from when they were still developing everything, though its odd how much graphics you can pack into a game in just 1 year.
Thats from thier pre-alpha phase. To compare, thats about the same phase SC2 was in when they showed the toss gameplay vid.
Good find. I prefer the SC Legacy one though. Too bad they took out many of the greatest features: Dropships landing Goliaths with FLAMETHROWER and MISSILES at GROUND TARGETS!!! Swerving air units The old Assimilator Unit Ranking Terrain Effects etc. http://sclegacy.com/content/starcraft-encyclopedia-4/starcraft-evolution-12/
I'm Speech Less When I Look At These Pictures I Can't Think Of Anything To Say. I Mean I'm Completely Speech Less!!
I think it is interesting to see how they developed and shaped the game over time and how much it changed. I'm glad the original Starcraft turned out how it did in 1998 and that they were able to fine tune it. I mean the final product looked like a completely different game than when they first started.
