The strategy you're describing is usually referred to as Big Money (see
this article on the subject); adding a +cards is a common addition to BM strategies (Smithy BM and Envoy BM being common ones). But the good news is, playing with randomized cards (like on Isotropic), BM-style strategies are only dominant about half the time (the other half of kingdoms being dominated by action-card heavy engines), and going pure or nearly-pure BM is dominant only very rarely (occasionally I'll see a board where Envoy BM seems to be the best, and there's been some discussion since Hinterlands came out about how double Jack of All Trades + BM seems to be really good, but that's about it). Almost always, even when buying lots of money is important, it's best to buy more than one action card to supplement your deck.
So, to get to a more practical point of view, it sounds like you think BM is boring. So do lots of people. There's a few things I can suggest to help out with this:
-Play boards that favor engines. If you're playing on Isotropic, you can use card constraints (though a lot of people don't like to). The Alchemy expansion is also very engine-dominant; you can buy it and use lots of its cards if you're playing in person, or check the box to bias selection toward it when playing on Isotropic.
-Play engines a lot, regardless of board. While sometimes a given board will obviously favor either engines or BM, lots more boards have viable ways of playing either style. If you think playing engines is more fun, play more engines! You may not always win, but sometimes you will, and you'll get better at figuring out how to best construct an engine (
here's an article with a few tips on that subject).
-Learn to appreciate BM. It might seem stupidly simple at first (buy one action card, then buy Province>Gold>Silver), but there's actually a lot of subtlety to how to best play BM-style strategies. Some
people over in the Simulation subforum have been working on optimizing that kind of play for a long time, and
it's still not a solved problem.
-In addition to there being a lot of skill and nuance associated with
playing BM, there's a lot of skill involved in
deciding whether to play BM-style or an engine. This kind of decision-making (looking at a board and figuring out what the best way to play it is) is really where a lot of the fun of Dominion is. Once you get good at figuring out whether BM is a good idea or not, there's a nice feeling of satisfaction that comes with picking out the optimal strategy for a board and beating your sub-optimal opponent with it, even if the actual strategy you end up playing is kind of boring.
Hope some of that helps you out!
