The Valiant Review (OGoL)
This game is good. If you know what to expect, then you can have lots of fun with it. Don't get fooled by the mixed reviews.
I played only the campaign, no skirmish or MP and it was worth it. The story is decent and no mission plays like the other.
You control a few squads and heroes with different abilities and a rock - paper - scissor system. In most missions there are only 2-6 units to control, so don't expect huge medieval fights like in Age of Empires. There is basically no base building. On a few mission you are allowed to build towers and palisades but this is it. If your squads are dying, you can retreat to a captured tent and replenish them.
During the campaign your heroes gather items and XP and you can to an extent complement them to fit your playstyle.
I played on hard difficulty (there is NewGame+ with nightmare difficulty). Some missions are way to easy, some way to hard, but it is managable. On the last mission I encountered game crashes during the last fight, but I was able to finish it despite the problems. Apart from those issues the game plays and runs fine.
Overall it is similar to Company of Heroes or Ancestors Legacy and it's well worth a try.
