Be very careful and look at the date of release before you think of buying this. It's 13 YEARS OLD!! The release date of 2001 is in very small print.
The videos above make it look like a modern game. However, these aren't in game graphics, just footage from cut scenes. When I bought this game, it was being advertised on the main Store screen as being "new!" However that is deliberately misleading and this has now become a very vocal and major issue of the way Steam is deliberately misleading it's customers (some are saying "downright rip off" on many gaming sites and gaming focused YouTube channels).
I find this very sad as Steam used to be held in high regard by myself and many, many others for it's integrity and honesty to it's customers.
As for the gameplay of WW3: Black Gold, it looks very dated now and has been left way behind by so many more modern games in the RTS genre. It just can't be compared to more modern RTS games in ANY possible way.
I bought this game and before playing it, went to visit my big time PC gaming neighbour. By coincidence, he was playing the game and was ranting how he had been "conned" by Steam and cursing the game and it's gameplay. So I sat watching him playing it for a few hours, hoping it would get better the further he got into the game. It didn't.
So when I got back home, I uninstalled it and never bothered with it again. So I haven't logged even a minute of gameplay on it on my own computer. What I saw at my friend's was enough for me.
So when I want an RTS fix, I go for Company of Heroes 1 and 2, Starcraft 2 (both of the already finished games of the intended trilogy), the Warhammer RTS games and the Paradox Grand Strategy games such as Hearts of Iron 3 TFH, Europa Universalis and Crusader Kings 2, etc.
So the lesson to be learned here is that Steam is quickly losing it's integrity and high regard in the gaming industry and so be careful to look at all the small print in the advertising for EVERY game it sells. Plus, assume "new" means the game is new to being available on Steam and not necessarily new as in made in 2014.
I really hope this isn't a downhill spiral and that Steam gets back to how it used to be which made it essential to all PC gamers.
