It was good back then, nowaday? not so much many of these so called devs are just trying to milk people into giving them money.
moreover most of their airdrop aren't even worth mentioning, I think trend has shifted, and what's left of these telegram games are just some mediocre project which sole purpose is trying to be rich and become cash cow for the developers.
I think this sentence is so incredibly illogical
"Promote TON blockchain" and then you have to send them
0.2, 0.5, 1 TON. Myself have paid some games but not many of them and now everyday you see a new game with the same sentence
"Promote TON blockchain" 
And you can also make daily transactions, I played dogs but very little and it felt legit and you didn't have to deposit money, but these cats, hamsters and others have been really ugly that take your time and money even if it's a small amount. And in the end for what? For nothing? And the reason they continue with new phases is to milk out more and more money right?
exactly, they are just trying to milk people in the name of promoting ton blockchain, what they are doing on the other hand, aren't promoting, but instead give bad impression to ton users.
