I don't see this as unreasonable. If there is an alt season, it's quite possible GALA will blow past this target, simply because rising tides lift all boats.
I've played their popular Town Star game and found it too difficult (though if I put in more effort I am sure I'd be fine). The issue is it takes a long time to build a town and some bad decisions can cause you to lose after having dedicated many hours or even days to build it. Still, the game seems to have a large and growing community.
they are listed in binance so it means, this has high probability to go up as they are just gaining the interest of the community. just look at how much their price last year. they started like about $0.001x and look at how much they are now, 47 cents. though they need to gain its ATH again. but the chance here is high. $1 is indeed a very feasible target. remember, this NFT gaming industry is just in the early phase. so it will further boost its popularity in the next months to come.
