Indie companies do put a lot of effort in details but I think replayability for a lot of games is a bit lacking. But still a big fan of indie gaming companies, at the right price a good buy.
I agree, hope they can step up their game because my interest in PZ is fading away slowly.
Depends on the game, I think. Both indie games I follow currently are not yet released, but so far I see high replayability. Remember, when Planet Coaster launched, Frontier was indie as well. (At least to my knowledge). Lately, it feels like they loose their contact to the base, including the player base. Can't really put my fingers on something, but if I compare communication even during beta and now it is visible, and even more so if I compare it from indie developers with Frontier. They don't turn into EA yet (thankfully) but things are not changing for the better.
Anyway, back on topic (kind of): With details it is a small line, I know. For me, having more fleshed out DLCs every 6 month would be much more reasonable than half-baked DLC every 3 month. If DLCs would be fleshed out more, in my opinion the demand for new stuff wouldn't arise as fast as well. Currently it feels like eating fast food: Makes you very happy for the moment and it is tasty, but you will be hungry a few hours later again. It's time for a well cooked, healthy meal or we will all get fed up with this game way too soon. I mean, not me, obviosuly, as I have yet to reach 5 years of buiilding in a Planet game while for Planco players it is same old, same old, but the people who actually want a management game and a zoo simulation aren't always unreasonable, when they complain.
And some details aren't even too hard to implement. I mean, speaking of the joeys, half of the animation is already there. I don't think it would be exceptional hard to take the animation and make it appear also out of the birthing scene. But parent to offspring interaction would make the animals already feel a lot more lively.
And speaking of the Australia pack (though off topic again), the problems with the editable signs are also what I would call attention to details (or lack theiroff) and are quite simply sloppy. And THAT is something I'd never thought I expierience in a Frontier game. Still have hopes though and hope they just take a breath, collect their concentration again and turn back to be a down to earth company that do care to release the best game possible. And looking at the last time I was in that mood with them, they will knock me out of my socks with the next big free update anyway.
