If you love strategy and are a fan of games that mix several genres, you need to check out Border Pioneer. It's a city builder, tower defense, RTS, and deckbuilder all rolled into one, giving you plenty to consider at any given moment. If you want more after exhausting everything you can from games like Bloons TD 6, give this one a try. Best of all, Border Pioneer is available at a slight discount now that it's out on Steam.
