It's a pretty good game in general for people who like things like Fallout 2 and such, however there are a few problems that just makes me not being able to recomend this game.
The first one is the developers not really listening to player imput. They have their idea of the game and they will not change things that are clearly bad design just because they are trying to be different... They at least do fix bugs and try to get everything in working order as soon as possible, but the development will not be influenced in any way, shape or form by the players even if certain mechanics are bad or things are not balanced properly.
And that pretty much is the rest of the problems of the game.
Balance between different combatstyles highly vary with some being absolute overkill and others not being good at all. Granted the game hasn't launched yet so there may be some more balancing down the line to make this better, however I wouldn't hope things will be balance at launch, in fact I don't expect them to be balanced in any other way than mods.
The game like so many others in the genre has a carry weight limit and very early on it will seem like this is ok, until you start finding things like sledgehammers and metal armor which weight far too much and make even a very high strenght character barely be able to carry anything... I can understand realism but a game is supposed to be a game at the end of the day and carry weight only do one thing which is breaking game immersion by forcing you to constantly stop what you are doing to go unload. This is made worse with the game having respawns in some areas.
Worst than that is the vendor system. Now many games in the genre have vendors with limited supply of money and this much is part of Underrail, but if the problem was that alone it would be fine, however Underail also features vendors who only buy certain amount of items and in limited quantities too. What this means is that you can never sell all your loot, you'll be forced to leave a lot of loot behind or wait for vendor reset which I belive happens every 45 minutes.
So what does this means? Well you've cleared a place, you've spent a very long time going back and forth placing all your items in some container with easy reach, now you only have to sit next to the vendors for 3 hours to maybe be able to sell everything... So yeah the game pretty much forces you to leave stuff behind. Now even if you leave stuff behind you'll still have more money than you'll ever need, that is not the problem. The problem is that if you are not rewarded to go out of your way and explore, you might as well just do the main missions and rush for the end. There is no incentive to go out of your way and do side questing nor exploring.
Remember the above problem? Well you still have too much money, that is yet another problem of the game. You can buy anything you need at any time which means the economy is not good at all. You'll only ever be without money very early on but quickly you'll go from no money to I can buy the entire store.
Then we come to the crafting. It has been made slightly worse in some aspects, it was made better in anothers. There are some feats now to improve crafting but overall, crafting still isn't worth that much. Crafting doesn't keeps you ahead of the curve. For the most part of the game you will buy/find better weapons than what you can craft and when you finally start being able to craft better stuff, you are really close to the end of the game. No point in investing in something that will only pay off in the end, not to mention that you won't even need the bonus.
And these are the major problems with the game. It really is a shame because when i first played it the only problem was the crafting. All other problems didn't exist (well there might still have been some balance issues but they weren't as bad). the game has a lot of depth to it, from character creation to character development and to how you engage in combat. The story is ok as far as I've seen. Definitly not Obsidian level by any means but still good enough.
The game had all the opportunities to be the next Fallout. Granted with a bit of a Metro spin on it. Unfortunatly the problems I described above just make the game completly unplayble so I'll have to give it a negative review. Maybe after the game is released someone will mod the game and actually make the game good and worth it's price but as it is. It isn't worth your time even if it was free.
