War of the Roses is an interesting game that sadly has many flaws.
While it seems to go to great lengths to get historical accuracy right on the weaponry, the combat itself is often laggy and only a few days ago there was exactly one server I could find that wasn't a duel server. In addition, you have to spend coins(Which you can of course buy with actual money) to unlock your items if you want to play a custom build. But at least you get free coins for playing. It's not a lot, but it's enough that you will have a decent progression to your goal if you have a single set goal(Such as a crossbowman). I don't recommend buying coins, at this stage it feels like throwing money down a well
Luckily, to play the game itself is free, and that is exactly what I recommend. The combat feels like it's similar to Mount and Blade but a bit more polished for multiplayer, but sadly there are some builds which seem to almost always work better than others. An example of such a build is to take the lightest armour and add a large axe. While this would in theory make the user very squishy and easy to kill, in practice there is enough lag that they are difficult to hit and often you will find your attacks pass right through them, but they still hit incredibly hard with that axe.
When you can find a server that's right next to your home, however, this one build almost completely disappears as they get wrecked with a single hit nearly every time you swing at them. Of course, there are more 'optimal' builds than just those, so you'll still have trouble and may feel like you're going up against copy pasted enemies at times.
In the end, there is a lot of good, and a lot of bad, but it feels from what I've seen like the devs, publishers, or both have given up on this game so it won't be getting much more good out of it. I'm still recommending it because it's a free alternative to games like Mount and Blade and Chivalry. It's nice, but that's all it is. Not really good but not really bad either, and I would say it's worth taking a look.
