A solid adaptation of the Yu-Gi-Oh card game with a campaign consisting of hundreds of duels from across the various anime seasons. It is updated to master rule 5, meaning that the controversial changes that came about with the introduction of Link monsters have been altered to allow for the viability of non-Link decks. It suffers from some crashing issues and odd omission of some options but is easily the best Yu-Gi-Oh game you're going to get right now.
Progression-wise, cards are unlocked by playing story duels, each duel gaining you a signature card from your opponent's deck. As you progress, booster packs are unlocked in the store that you can then purchase with credits that you also earn by dueling. No microtransactions of any kind are present, this is entirely in-game currency. In my opinion, the rate at which these credits are obtained is slightly slower than I'd like but definitely not unreasonably low. Generally you can get 2-3 boosters per duel victory so you can go on a spending spree after a few games.
It should be noted that there is no way to purchase individual cards and duplicates are possible, meaning that hunting for exact cards can be rather tedious if RNG isn't on your side. I would highly recommend looking up a card list to find out which booster packs contain your desired cards before you go spending credits randomly; at least then you know that it's just RNG and not the wrong booster.
The biggest issue with Link Evolution is the performance. While it runs fine for the most part with very basic visuals, the AI can sometimes completely stall itself out and take 30+ seconds to decide what it wants to do. This is the most prevalent during duels heavy with Link monsters (VRAINS campaign) wherein the AI can in some instances be stuck considering their move for upwards of 2 whole minutes before finally starting to execute it.
This AI issue isn't incredibly common, but the bigger issue is definitely crashing. Depending on what kind of deck you are playing, there is a chance of crashing when certain card effects trigger. I find that anything that opens a search menu (e.g. Pot of Duality) to root around your deck has a small chance of crashing the software instead of actually opening the menu. I have also experienced this when you summon a monster that plays a cutscene (e.g. Exodia, Dark Magician, Blue Eyes White Dragon). By no means is it every time you play them, but if you run decks that are heavily themed around deck manipulation or just themed after certain notable monsters, you run a risk of losing your progress in the duel at random.
The final issue is the aforementioned cutscenes; several second clips that play when a particularly notable monster from the anime is summoned onto the field (or in Exodia's case, is assembled in the user's hand). The first time you see them, they're a nice little flourish. But when you're seeing multiple unskippable cutscenes in a single game because you're playing a Dark Magician deck vs a Blue Eyes deck, things start to drag a LOT. Definitely be on the eye out for a patch that allows you to disable these things.
Pick it up if you're a die-hard fan of the series, for sure. Just be prepared to maybe start a few duels over after an unfortunate crash.
