That said, the second best modern model is probably theirs. They sell stash tab space (item storage) and cosmetic items only.
They do not play psychological games that many free to play games do. I imagine that when their revenue starts to slip, they may go down the more dubious road as is the normal pattern. But for now, it has my approval.
I'm completely fine with that monetization since you still can't beat better players with money and you can still do everything without spending a penny. You at most get a tiny MMR inflation for a week or two if you buy every new hero on release (which wasnt even that often) and that was nowhere near enough to jump a higher league. Hell, given that it still didn't make them enough money maybe it was too little monetization..
I've really come to enjoy Good old Games https://www.gog.com
They have Diablo 1 (+ Hellfire) available for 9.99 (but goes on sale)
(That said there's a huge "Do not sell my personal information" link on the diablo page)
I have enjoyed torchlight 1 and 2 quite a bit. It's been a while since I played diablo 1/2 so I can't compare in my head. I recall there was more clicking in diablo.
So... You play the game to get loot. The more you play the more loot you get. So of course you wanna save the loot. So you put it in your stash( all players start with 3 stashes) , for safe keeping. The better it gets more loot you get. The moment you start getting the feel of the game (it is one deep game) you discover trading with other players. To trade with other players you discover premium stash tabs.... One tab is around 5 usd. But u need to buy game coins so u always have almost enough for one more stash.
So a premium tab is like a store front where u can display items for sale to other players. So naturally one starts buying more tabs. And more tabs. And then there are the specialty tabs that organize all the loot. Coz why do it manually when u can pay for a stash that auto sorts loot while you gather even more loot...
And suddenly you realize. You have 27 stashes for a total value of 300 usd... Most you have bought one the weekly stash sale.
And that is how PoE is financed. No walls no hidden stuff. Just loot.
yeh also cosmetics in case you wanna look good gathering all the loot.
Of course, I’d be remiss to point out that you really need to shell out to get enough stash space to prevent frustration. One of the $60 supporter packs will get you just enough points and also give an alternate look if you need it. But for the same amount of money as a retail game you get a lot of content.
Namely, stash tabs, as inventory takes up a lot of space. It's not too expensive though.
Though, some players are a little sore over how they seem to be adding very specialised tabs in new leagues. There is of course a perverse incentive at play to design content to require tabs that can be sold to us.
I'm playing both and in comparison to majority of MMOs around both offers something I'd describe as fair microtransactions.
