Yeah but Gwent to me feels like it boils down to straight mathematics, at least in the Witcher 3. Rounds are like a math puzzle, when to lay your cards, not necessarily what cards to play. (Because you boil your decks down to exactly whats useful.) Yeah sometimes playing a weather card at this time versus that can win the game, or one of the few nukes, but that ends up being true in most matches.
I feel like if there were more cards with abilities (and I know you'll get plenty by the time you're done) it might be more interesting. But I dunno. Every time I'd get in to a game I feel like the outcome was predetermined except for a couple select cards and when they came up. I played MtG for years and so I'm no stranger to "doing the math" each turn. But where Magic felt fun and inspiring and explosive sometimes despite the mulligans, Gwent often feels like it methodically plods toward a foregone conclusion. Especially in the beginning. Because the entire match hinges on what everything totals up to at the end of a round, and your deck does not refresh between rounds, I dunno, minute to minute decision making and choice feels limited. "Hold 'em or fold 'em" is I feel the most relevant decision to make in Gwent. Spending just enough cards to weaken your opponent so you can blow your load in two rounds is the kind of thing that's interesting against people, and boring as fuck against the AI.
It's sort of the game vibe I got from Frozen Synapse and why I didn't like it. Coldly methodical and calculated. I think Gwent appeals to people who like tight, minimalist gameplay. For me though, especially in card games, I need a little more variety and spice.
