Probably gonna jinx it by posting about it, but I’ve started playing Minion Masters last week – it’s free to play with ingame stuff, no clue if it’s pay to win, so far I haven’t felt the need to buy anything. I’m only like 20 games in (2 hours) but it’s fun for a few minutes per day. Of course there’s free login stuff and small quests like “Win 3 matches” but also neat stuff like rotating free heroes (I think LoL also has this) and then some “Win 5 matches with the rotating heroes”, and several different tournament and ladder modes.
Oh, what kind of game? I’d say it’s realtime Magic: The Gathering. Two opponents face each other, you play the cards from your hand (mostly creatures, some spells), those run towards the enemy and hopefully kill their minions and then life pool. If it has strong MOBA vibes, I am not feeling them. It’s quick and fun and nothing of the annoying weird stuff, but I’m way down in the league. Anyway, fun game – recommended.
