A few years back, Skyrim was one of the best RPG games out there. Great graphics, decent story, and a mod community that continued to keep the game interesting. Dragon's Age Inquisition was also pretty good, but strangely, the developers decided not to support the mod community.
Recently, The Witcher 3 was released. This is a role-playing style of game that has you building skills and making choices as you progress. I had tried previous Witcher releases and was only moderately enthused. This version has you playing as a witcher of some fame from the previous titles. A witcher is basically a mercenary for hire that deals with supernatural beasts. The world you live in is similar to that of medieval times and has an ongoing war raging between various factions, none of which are clearly the "good guys." In the midst of all this upheaval, you are trying to find your adopted daughter.
This game has everything a good game design for adults should have. While some might focus on the great graphics, I appreciate the story and the morally ambiguous choices you have to make that will drive the story. Often there is no clear "right" choice. AND if you choose to , say, fight some obnoxious drunks and kill them, later on, the bar owner may just call you out in a bad situation. Every choice you make will result in a change in the world around you. Clear out a demon nest in an abandoned village, and peasants return which can then offer you people to trade with, etc. Your choices can even lead to "romance" which is pretty tame by today's standards but does have brief nudity. There are also two women vying for your character (sorry women, there is no option to have a female avatar like Skyrim or DAI). Your choices can lead to a relationship with one of them, or neither. You can choose to be a badarse cruel mercenary, or you can choose to be "helpful". It's all up to you.
The story is told through in game rendered cut scenes which do not break the flow of the game. Whoever directed this aspect of the game did a superb job. If you have a twitchy finger and just want to kill things, this is probably not the game for you. Side quests are plentiful and can lead to things that you would never had found just following the main storyline. Another kudos to whoever did the animation for both your character and the beasties. Very lifelike and well done. The environment is well rendered with weather and time changes as well as the accompanying sound effects. Your horse hooves make different sounds as they move from firm trail to puddle. Attention to details like that make this game stand out. Voice acting is also well done. At times, the game is more like an interactive movie than an action game. I like that, your mileage may vary.
About the only things I can say negative is that for PC versions, the control system is not optimal. A gamepad would probably be much easier to use. You will need at least a quad core processor to run it. Other issues: the inventory system is a little clunky, the lore for this world can be a bit overwhelming, the game within a game of Gwent is unnecessary, and the "hunt the foozle" quests can get repetitive (which is pretty common with any role playing game).
Overall, I give it a 9.5 out of 10 If you like RPG's and don't mind swords instead of laser pistols, you may want to check this one out. Plenty of vids on youtube of gameplay and many reviews of the game itself. Check it out
