The first RO was an indie project but not sure you could still call it indie developers, but more so a small studio nowadays. I'll concede that RO2 (great game) is practically an AAA (for a 2011 game) and that things like Squad look pretty good (project reality team), same with all simil games. Biggest issue with this kind of titles, is that they have a niche market (simulators) and they also have a way smaller team (Relic's has 4 times more people than Tripwire).
For you, as a consumer, it might look like all of them are AAA games but they are competing on different leagues. If Relic somehow ends up been a 50 dev studio with no daddy Sega behind it's back, sure it might have a different monetization model.
I'm also a modder mind you, so not just your ordinary usual user.
Anyhow, I'll give it to you for now until the Iron Harvest devs prove themselves and their new game in the RTS market.
I am sure that a small indie German game development studio can beat Relic's triple A titles with SEGA behind their back.
And you know why? Because they're actually listening to their god damn community and not doing it for money.
Doing something for money might be more realistic in our world but that doesn't mean that good ideals can't live long and prosper as well from time to time, and that's exactly what Relic did with DoW and CoH, and what these guys are doing with Iron Harvest again.
