Oh and other things I like, Obsidian gives you choice of RTwP or TB and then level scaling which I said a resounding NO !!!!
Upscaling is good, as I've said.
As for the game mode, I recommend RTwP, at least for your first game.
Experience the systems like Josh initially imagined.
Many systems are largely meaningless in TB mode (like Dex, Armor Speed - wear the heaviest one, D'oh, Weapon Modals that impact Action Speed - why would ever not use the +20 Accuracy Arquebus one for example?), TB mode skews the Balance between martials and casters in favor of casters (what is better: a sword swing - or even 2 - or a Fireball? - cause now they both take 1 round to make) plus passive-reactive martial builds (Retalitation and Ripostes) - off-turn damage is good, enemies are often a bit too bullet spongy for my taste.
