I just think that overall Drew (should) will find this easier - I don't know how interesting it will be necessarily with the whole thing being so cutscene heavy and Drew not wholly understanding things, and Dan mis-explaining some things (I understand though, as trying to explain MGS lore on the spot would be fucking impossible)
It had been years since I thought about the Metal Gear series before I played 4. 3 kind of killed my interest in the series--even though I now appreciate it a whole hell of a lot more than I did at the time. I still found 4 pretty easy to understand,. Well, for the most part.
Royal is definitely easy mode for Demon's. But on my most recent platinum trophy run, I went royal. The game hadn't quite perfected the idea of boss runs, so most of the time a boss death meant that you'd have a substantial run to the fog gate and it would probably be a little tough to get around some enemies. The levels themselves are definitely more challenging than the bosses. But it is pretty cool that every boss has a different mechanic, something the other games in the series haven't been able to replicate.
As with most old games that spawned franchises, the originals can be very rough to go back to.
People are so sensitive about being goofed on for playing video games. Video games aren't your identity, they are a hobby. In high school, some people would crack a few jokes about me constantly having my nose in a book, but I didn't care. I didn't have some nebulous sense of reader pride.
