Probably not as fun today due to how derivative it seems, but underneath is a decently working game with a couple of nice challenges. Just be careful of the difficulty spikes.
I'm sure this must have been fun when it first came out in 1990, but today it feels extremely clunky and weak compared to its successors. Still a solid fundation.
I know having 80+ characters in the game is more than plenty, but I wish the game had more variety in game modes. WoL was incredibly boring after 2 hours and playing normal matches (either online or with friends) will get stale after a couple months.
What started as a genuinely fun and addictive game turned into a perplexing snoozefest thanks to the devs constantly changing cards left and right every single month, creating an environment where no creative or interesting decks are fun and where money spent is made worthless.
