Stronghold 1 is love, Stronghold 1 is life.
I love this game, from the age of ten all the way to now, I have loved every single second of it.
The campaign is challenging and fun whilst keeping you thinking of new ways to take over that pesky Pigs' castle (Still haven't been able to get past that mission). I've played a few multiplayer games and it is quite polished. There is no lag, and if there is, it is either connection lag (99% of the time) or your computer is a potato (1% of the time).
To this day, I say to myself, "These graphics are perfect for this game". I have absolutely no problem with these 2001 graphics, plus the HD remake makes it even better by adding bigger resolutions.
The combat is also quite amusing. Woodcutter VS Cavalry? Sure, why not. Don't get me wrong, woodcutters are OP as ♥♥♥♥. The unit pathing is also simple yet effective and is much, much better than Stronghold 3 and some other games that I have played.
The Map Editor is also simple yet effective and has allowed me to create some pretty cool Free build maps, siege and invasion maps. It also allowes you to choose what buildings can be built, how much resources you start with and events that happen throughout that particular game.
Overall, if you are thinking of getting this game, stop thinking and spend the $6 it costs to buy it, because for $6, you can get hours and hours of enjoyment, just like I have, out of this game.
11/10 would build stone stairs up mountains again.
