As with all region-focused expansions for Europa Universalis IV, the first question you need to ask is whether you want to play as a nation from said region, because If not, you should look at another expansion instead. However, for those interested in playing as Muslim nations, Cradle of Civilization has plenty of new mechanics, features and events to make it worth your time and money.
Jade Dragon adds precious little to Crusader Kings 2, which would have benefitted much more from a playable and visible Chinese region. This expansion feels far too feature-bare for its price tag, and even at a smaller price point none of it feels really impactful. Even when you have access to the China menu, you'll likely find yourself progressing via other means.
Way of Redemption is all there technically and functionally, but it's empty and short on content. Every moment spent playing, the obviousness of it being an attempt at a forced e-sports success hangs over the experience, which is pretty dull to begin with.
Battlestar Galactica: Deadlock is a massive treat for fans of the franchise, but even if this is your first exposure to the universe, it's well worth your money. It's a sufficiently deep, extremely fun and good looking turn based space strategy game with fantastic combat and a content-rich campaign.
ShadowHand takes an old game with a reputation for dullness, and dresses it up in an elegant Victorian English RPG coat. Somehow miraculously, it works really well. It isn't a reinvention of the wheel, but the sense of personality the game pack in addition to being simply fun definitely makes it worth the time and money.
Tesla vs Lovecraft is stupid fun, reveling in nonsense and bullets. The rapid, frantic gameplay delivered in snackable portions underscored by a fantastic soundtrack makes for a hugely entertaining experience, even if it gets a tad repetitive after a while. We'd say blasting Lovecraftian horrors as Tesla piloting a mech was never this fun, but then it wasn't ever done before.
Iconoclasts is a kind of game that no AAA studio could ever have made. It has all the mechanics, visuals and other easily judged elements that a video game needs, and nailed down really well too, but it also has a less tangible feel to it that just endears it to the player. Even among other nostalgic pixel-art metroidvania games, this one stands out, and ought to be remembered as one of the indie greats.
Assassin's Creed Origins: The Hidden Ones doesn't change much, which isn't a bad thing considering how good the main game is. It makes small improvements while keeping the same formula, while telling a meaningful story set in a new land as beautiful as ever. Anyone who enjoyed Origins is bound to enjoy The Hidden Ones.
