I can't prove you entirely wrong, but it isn't failed, yet. As turned out GLS team was working on paralelly on Arcade Colony platform, too. (Looked like they worked only on that, instead of GLG in the last half year.)
Nowadays, they are shifting back to GLG, and doing some upgrade for gameplay. (Even if they stuck with this playable turn-based thing, instead of manager mode, what is in my opinion easier to do for small team like theirs, and more popular, better fit for NFTs, tokenomics.)
The 2nd version will look like something like this. At least, 11vs11.
GLX only real function atm: staking it, so you get some GLGT daily, and in ranked rewards mode, you earn more glx, by staking more. (If you got over 10k staked GLX in march, april, you got Arcade Colony token 1:1 airdrop, too. Many people didn't, don't know about it.)
GLX is not only for the GLG football game, but for hole GLS, what supposedly will include more sports related games. Atm, that provides its real long term potential. If more games come to platform.
Currently, there is an ongoing weekly manual tournament for 8 weeks (this one is 3rd week). Approx. 30 people playing that. Anybody can join, who has the franchise licence, and cards for a team, no staked glx requirement. (in 3 divisions, levels). There are weekly prizes, top8 get prizes in each divisions (weekly total 75k glx and 750 packs), so atm almost everybody. Weekly 10-16 matches. + there is overall LB prizes.
Lowest division weekly prizes:
In case you would try, registration is on GLS Discord, each week till Monday 8PM EST. DrZoom and Khan organizing it.
Well, I am not sure if 11on11 model would help, as long as the gameplay remains more or less the same, but I am glad there's still something going on :)
I guess my weak team cannot really hold a candle to the other participants, so I'll pass on the tournament.
There are new players in the lowest division, with single bcx cards. Hopefully next one will be in relegation/promotion system, so newbies don't have to play a single match vs. much stronger teams. (They are giving away through these tourneys the S1 league, cup 2.5-2.5M glx reward prizes. This is the first one, so even if you don't like gameplay, how most of us, it's still worthy.)
About gameplay: Turned out, they got plenty ideas from Football, Tactics & Glory turn based football game. (I never heard about it, nor know 1 more like that, but if they will push similar marketing, like this FT&G did, who knows...)
