I think perhaps micro-managing layered limit orders to try to squeeze the last penny out of multi-kilobuck index ETF purchases might be the right way to gamify responsible investing, though that does have the danger of soaking up hours during the workday, so there are negative consequences. Maybe they way to go is lump-sum investing into some bond ETFs with gamified rebalancing into an age-appropriate mix of bond ETFs and broad equity index ETFs, following some pattern similar to value averaging for the rebalance, rather than cost averaging. It shouldn't actually be too hard to get something that has the right balance of feeling like real work, being relatively difficult to screw up (or the most common errors having little long-term effect), and out-performing dollar cost averaging. This isn't investment advice, and even if it were, you shouldn't take investment advice from internet randos.
