Yeah, it is interesting to ponder how much the game changes by a seemingly simple detail like how the pieces are generated. If they are generated uniformly then it is certain that the player will lose sooner or later (getting too many S or Z pieces in a row). It also has been shown that such a setup makes the game NP complete. https://arxiv.org/abs/cs/0210020 https://arxiv.org/abs/cs/0210020 It's way above my head but intuitively it feels like any randomization based on the bag model would give rise to optimal strategies, even making it possible to play indefinitely. PVP play as you say of course makes it much more interesting. It wouldn't surprise me if the strategies for playing well are just as deep as for playing Go or Chess.
