Any weird/controversial opinions? I'll start. Before the remake, the best version of Resident Evil 4 was the Wii version. The Wiimote controls old Resi's tank controls better than any other controller at the time. The PC version had a bunch of little bugs and detractors that the Wii version just doesn't have.
I'll extend this by saying that the Wiimote is actually pretty damn good for shooters, and particularly good for accessibility. Not having to cramp up my hands to press buttons is awesome for having arthritis. Aiming with the Wiimote and moving with the nunchuck just feel really natural, you barely have to move your fingers for anything.
The sleepy plot-twist at the end could have only been imagined as good in a dream. It felt so lazy and uninspired I didn't even bother giving X-2 a try.
BUT FFIX and Tactics: War of the Lions are definitely the best ones.
