I realised that so far this thread is just discussion rather than suggestion, but hey, something might come out of this.

I completely agree with you on everything, but I don't think there's gonna be much change in how things are moving.

They're probably pulling not that bad of an income even now, enough to get decent return anyways. When I was HS I saw many newbies buying TC from TB store, often as much as 100$ worth. Now add all the Toriprime subscriptions, profile customisations, you're looking at really good numbers considering game's size. That might be good enough of a reason for hampa to be satisfied with how much he's getting from this and he just doesn't see any worth in investing that money. Similar situation was seen with PUBG developers until recently, as well as many other indie studios.

If they were to expand their team, they would have done it before starting to work on TBN. Hampa is working on it by himself and that's probably just his preference above anything.

In terms of advertising, games don't get that much exposure through cheap web adverts anymore. These days paid YouTube or Twitch promotions are go-to for any indie game, but those are expensive and usually not that reliable because you're not really in control of what's being covered for that price. The rest is through partnerships, but I think it's pretty obvious that Nabi has no partnerships with anything, and in its current state they have nothing to offer.

Nabi had a chance to prosper in 2012-2014. Now that TB hype died down it's an uphill battle to gain any sort of exposure for a relatively low cost. It's really sad to think of it like that, but unless TBN proves itself to be revolutionary in current game standards, it's not really bringing any more success to Nabi.

Gaming industry has greatly evolved in the way that studios are being managed and promoted over these few years. We have to face the possibility that Nabi might be outdated to the point of no recovery.
