Splinterlands is one of the best case to compare.
in terms of ROI it's very similar,
in terms of time spent to play, dcity requires much less time
in terms of game rules, let's say it's similar even tho splinterlands is probably much more complicated
in terms of governance, it exist in dcity, will exist in splinterlands
in terms of governance, it requires a lot of time for players to learn it, here we are after year+ from making governance, players in dcity still learn about
in terms of cards liquidity, very similar, super hard to sell 10k$+ of cards in both ( anyone wants to buy 65k$ cards in splinterlands from me ? )
in terms of UI, we tried to avoid splinterlands mistakes, and make it easier to manage nfts (transfer or market operations at scale)
