If you want a tl;dr verson, go down the the very bottom of my post. Otherwise, you can read this mess of an essay.
Since you listed strategy as your preferred choice, I’d recommend Romance of the Three Kingdoms: The Legend of Cao Cao, which’ll be known as TLCC from now on. TLCC is a turn-based strategy game based on one of China’s most famous historical novels, Romance of the Three Kingdoms. However, you really don’t need to have encyclopedic knowledge of the novel nor Chinese history in general, as the game gives brief information of every character it has. The game’s beginning tutorial gives you the basics of the game, and as you level up, sometimes there will be more advanced tutorials you’ll go through. The game’s tutorials give a much better explanation of the game’s mechanics, so I’ll give you a summary of them. There are a few types of currencies that are used in this game, which are Silver Coins, Rations, Gold Coins, Imperial Seals, and Fame. Silver is one of the two currencies that are the bread and butter of this game, the other being rations, while Imperial Seals are a currency you get by completing battles. Fame is another type of currency that you obtain by winning battles, but since I never use them, I consider it to be a useless currency. There are three main types of troops: cavalry, infantry, and ranged units. Cavalry generally have high mobility and attack, but poor defense, while infantry generally have average defense, attack, and mobility, and ranged units have average mobility, poor defense, but great attack, unless if either cavalry or infantry are right next to your ranged units, which in that case, you’d better put some distance away. The exception to this is mounted bowmen, which are ranged units that’re considered cavalry. Another ranged unit I should give notice to are catapults, as from what I know, they are the only unit with poor mobility along with their poor defenses, but they have the best range and attack out of all ranged units. How you unlock characters is not by stupid lootboxes that most asian-developed games are somewhat infamous for, but by banners. Banners are kind of like tech trees, in that you “research” characters before you buy them. Banners are unlocked by either conquering a certain province or by using gold coins. When you unlock a banner, you can either use Imperial Seals or Gold Coins. If you decide to unlock characters via Imperial Seals, then you also have to buy them with Silver Coins. There’s much more to explain than this, but I explained what I think are the most vital aspects of the game.
tl;dr, I’d recommend TLCC to you.
