Pure Wizard for my first time through any RPG (for fallout, it was using science, repair and energy weapons primarily)
You can kind of gauge how much thought the devs put into the build variety by doing this. Plus, I like magic as a theme.
Games like Baldur's Gate and Fallout 1 are horribly imbalanced against a mostly magic playthrough at the start. (seriously, a level 1 mage has one cast of two spells each rest. otherwise you're smacking things with a stick or throwing rocks)
Morrowind is heavily weighted in favor of magic, to the point that not using it is a challenge run only possible through some weird manipulation of encumbrance and acrobatics.
Elden Ring is one that I'd put nicely in the middle. Don't come at me with kitchen sink buffs and comet azur one-shots. Those characters are the glassiest of glass cannons, run out of steam after one shot, and are prone to missing if the enemy is slightly agile.
They're Megumin.
