I will never say anything negative about Starcraft because I feel as though it is one of the most perfect games ever made. There is a reason why it is still popular around the world despite the fact that it was released 20 years ago. The game is perfectly balanced (except for the High Templar's use of Psionic Storm, which only the AI can BS with) and this is the reason why the game is still relevant today. However, this "remastering" could have been so much better than it is.
The upgrade costs $10 and to be honest I was initially excited until I played the first mission only to discover that it is exactly the same as the original campaign. Literally nothing has changed about the missions at all. Sure the cut-scenes look really pretty now but for the most part I just skipped those anyway (if I wan't to watch a movie I will do so.)
Basically this is just an aesthetic overhaul and allows the game to be played in 4k, which is a bit superfluous for a 20 year old game methinks. The audio is revamped as well, which I didn't think was necessary either because there was nothing wrong with the original soundtrack.
This is a really kick-ass trailer and makes me wish they would make a Starcraft movie... be careful what you wish for I guess because we could end up with a Warcraft failure. This doesn't change the fact that I really don't feel as though the updated graphics are worth the $10 cost. I think that they really could have kept the fanbois happy if they had updated the graphics AND introduced some new campaigns as well. They could have even charged more than 10 bucks if they had done that and i would have gladly paid.
TL;DR
If you look at nearly any forum regarding this upgrade you will see a bunch of people like me complaining about how they feel duped by the remastering since it is just an overhaul of the graphics. Nothing about the gameplay was introduced and the campaign is EXACTLY the same to the point that enemy units are actually positioned in exactly the same places as before. This just seems like lazy programming to me.
My overall take on Starcraft Remastered is to spend that $10 on something else.... like beer.
