+ If you are into firearms, this is a goldmine. Hundreds of models with new ones released periodically, with complete disassembly, reassembly and demonstration of operation, with - for some models at least - a selection of example accessories.
+ Very thorough; probably little to nothing else on the market is as accurate as this is when it comes to the depiction of firearms
+ There is DLC unrelated to guns for those interested in taking apart other things; such as cars or skeletons.
+ The lifetime access, while expensive, is very, very, very much worth its price if you know what you're looking for, and if you just want to skip the whole Facebook-game-aspect of earning "points" (see below)
+ Shooting ranges put you in a first-person perspective; and pleasantly enough, ballistics are also correctly replicated; this is NOT a hitscan game and they did put effort into this
- Lack of blank backgrounds which would probably be easier on the eyes... though this is a minor gripe.
- The "Paint" feature, part of the latest update (as of the time of this writing), while interesting, is currently lackluster, with a very limited amount of stickers and patterns (some of the tackiest ones being DLC!).
! It's... hard to call it a game at all. It's more of an enthusiast's tool; the appeal is very niche. See below for an in-depth explanation.
Notes and gripes:
I "recommend" it solely based on my bias ; being a long-time firearms enthusiast, this is both an interesting toy to play with and an useful learning tool, but it's only going to be that way for you as well IF you are into guns... and mayhaps if you get the rather expensive lifetime guns access.
The free to play aspect may seem nice, but the point unlocking requires a little bit of grinding and way too much time on your hands. While it may be fun for some, it may be worth pointing out that this is the sort of thing I expect from a Facebook or mobile app, not a game on Steam (which it actually also is).This falls in the usual "time/money" problem of free to play games; either you spend time to grind away and get the Exp to unlock progressively everything, or you spend money to get them right away.
If you want something of a "gamey" aspect, the shooting ranges are the closest you'll get to a proper game, but unless all you want is shooting targets, bottles and soda cans, this may feel like there could be more that can be done with this, yet there just isn't... Although the RPG range was pretty damn cool, i'll admit as much.
Whether or not this is worth the cash depends entirely on how much value you put in having a tool such as this, which may or may not be directly influenced by your personal affinity and love of firearms.
For those looking for a "proper" game, you can safely avoid it, you may be sorely disappointed.
An extra note which concerns the Paint update; since this has also enabled Steam workshop for this game, allowing anyone to upload their combinations of guns, colors, patterns, and incredibly limited selection of stickers. While in theory this is a nice addition that may allow WoG players to sink a little more time in devising their eye candy for their favorite boomsticks, in practice it's done pretty poorly; as I said before, the very limited choice of stickers and patterns and the lackluster color options turn this feature into something more of a curiosity and less something particularly fun to use.
I would've much preferred having the ability to download templates and paint them using Photoshop or something similar, and use WoG as a sort of 3D renderer. Considering that the model quality is sufficiently high and true to life, it would GREATLY increase the possibilities, and allow potential gun artists to come up with real masterpieces. There is something to painting guns, if one's taste isn't limited to tacky gold guns that have been done to death (yours truly is guilty of it as well) or silly CS:GO-style paintjobs which have their place in a toy store more than in an armory.
But all in all, the Paint feature is just a part of World of Guns, and not the most interesting one. My primary reason for using WoG is because it is a fantastic learning tool for the firearms enthusiast, and for having virtual access to guns I wouldn't even dream of seeing in real life, let alone fire or disassemble.
Parting thoughts: Maybe Noble Empire should take the opportunity to develop some sort of game using these ultra-accurate models? That is, if the licensing allows them. Between a purely educational tool, which WoG is, and a proper video game, there's a chasm and certain firearm manufacturers might not find it all that fun and dandy to have their perfectly replicated, 100% licensed and trademarked designs and brand names depicted in a video game.
This is nothing new; many games have resorted to just not putting the brand names, logo, or even actual names, and some manufacturers have been known to do lawsuits over it. An easy example is Glock; you'll be hard pressed to find a game depicting or naming a Glock firearm that is actually properly licensed by Glock GmbH (Usually, instead of "Glock 17" you will see "G17", and so on). A counter-example is Walther; they LOVE their product placement in 007 movies and video games, and Walther guns tend to be accurately and properly named in these games; just to show you that gun manufacturers are no different from Coca-Cola, Chevrolet or Apple; they know product placement is big money.
