These are games that pass the test of the FTP non awful test (I am broke a lot, so i cant afford to spend money on them )Pah of Exile:
Imagine a version of D3 that did not get screwed up and made with consoles in mind, a game that is not afraid to let you make decisions and the bad ones to. And besides all that be a very good example of its type, and a very fair FTP model. Warframe:
very fair FTP model, you can prty much get everything in the game and not pay a single dime if you feel like trading and wheeling and dealing a bit. Its... by all fairness this is an older better version of destiny, and cooler by a lot.Star Trek online:
It is a nice mix with some problems but a decent FTP model, if you are not to worried about the end game witch is a bit nebulous. But if you just want to enjoy the story lines and play some space ships its a nice way to spend some time.
On the World of Tanks vs Warthunder i would argue that while on the first glimpse these might look like similar games, they really aren't so much. Its kind of like saying Unreal Tournament and Counter Strike were the same game. Yes its been a while since i played FPSs and yes i am still going with the analogy
But if you enjoy WoT you might want to keep an eye out for Armored Warfare, there are some promising things about it.
