game concepts are still similar like capturing bases and open world with a good written antagonist.
however they finally went with a written character to play as again so the story can be more fluid.
there are weapon changes and rebalances. I'm not a fan of the supremos, but appreciate the creative direction.
getting money is a challenge compared to the rest of the series, so you can't just get a god tier gun in the early game like in 3. I think this is more to force the microtransactions (which is complete bs for a story mode). however this was a much needed challenge tbh. stealth was getting too easy and with the weapons like the bow finally getting nerfed compared to previous games.
There is enough changes in the game that i'd say make it worth the money, but i have gripes with some of the artistic direction in supremos and the fact that microtransactions are a thing.
if you think the previous far cry games were too easy, then play through this without the tank. I'd say just use helicopters or planes, but you have to deal with AA guns first which makes it much more balanced and encourages exploration
