It's worth to play free games, but its still depend on the game that the developer created, some of the free games are not good but not all, i always look to the youtube for the gameplay of a certain game, so that i will know if its good or not.
1.)Check the reviews (positive or negative) if positive then it's a good hit. 2.)Ratings 3.)Check how many backers during the KS phase. (But not all games had KS) 4.)Do you like the game? If yes then it's worth it. 5.)What type of game? Is it Action, Shooter games,Strategy , Sport , racing ETC. (Which do you prefer.) That's how you determine if the game is really worth it.
I usually find that games that are not free ever are those who had higher investments in the initial development (also usually have more bills to pay for server upkeep), that needs to be payed off, which usually led to better gameplay. Those that are free usually had less in initial development and led to poorer gameplay, unless they cheese tactics with virtual currency.
Am ok with free games, as any type of games, there are good and bad, and agree, as long its not pay to win game, it is worth
Free games are definitely worth it. For example, warframe and fortnite battle royal, these games are completely free yet you can't find any difference between them and a paid game.
There are free games that are worth playing and then there are free games that are worth trying out. Just pop in and try one out.
