The randomization is nice enough that you don't feel like an because you ended up opting for a bad build. Although DC has a lot more customization freedom (you can literally play in 'Custom Mode', where you have a lot of control over your builds), RL2 doesn't disappoint.

For me, the customizations are satisfactory, and it is one of the two roguelite games that i consider to have great customization (the other game is Dead Cells).

Nothing gets left behind and there's no penalty for what you prioritize first (but it recommends that you level up armor, life, and the percentage of gold you get from traits). Well, you have control that you level up first, but at the end of the day, you'll end up 100% upgrading the castle over time. The reward, in general, is leveling up your castle ('base building' in the game is pretty basic, nothing complex), which practically strengthens your classes. It's a game that, in my view, rewards those who persevere and make an effort (That is, you don't need 'high skill' to enjoy the game).

While RL1 is more of a niche game, RL2 is much more casual in approach (the 'House Rules' system makes the game even easier.
