I do think a huge world with an engaging and dense design can still be made worse with size. In some games like Skyrim, Breath of the Wild or GTA 5, you could probably drop me anywhere and I’d know where I was, half due to good and differing region design and half because the map isn’t that big.
Back in 2015 I’d dream of a GTA 5 expansion that adds San Francisco and Las Vegas to the map, turning the north and east of the map in to a 500 yard straight of water, but in reality, two more large cities and their surroundings suburbs and wilderness would have never kept it’s memorability like the first region.
Green flame blade is a great horde killing spell while still feeling cool. IMO everyone picks booming blade because it’s more useful against single targets, which is more fun against a larger range of enemies, from bosses to your equals, plus thunder is rarely resisted compared to fire.
Some people implement minion rules where overflowing damage from killing a weak enemy flows on to the adjacent enemy, which of course is simplified and incorporated into green flame blade. One of the hardest things to capture in the standard D&D rules is that in fantasy, the warrior (Aragorn, Holga, Achilles) typically cuts down hundreds of mooks while the mage battles the giant powerful monster who cannot be defeated by a sword (Gandalf Vs Balrog). In D&D, either it’s totally inversed or the mage is better at both, largely because spells like fireball suit both situations better.
Green flame blade is a very easy option to balance this scale, albeit via magic.
