DMC V finally got its hooks in, so curious about checking out the older games. Definitely want to play 3, but are the first two also playing? Or better to just get 3 separately?
1 is good but clunky but DMC3 is peak DMC and the DMC3 Switch topped it with the addition of realtime style switching like 4/5 which the DMC collection don't have.
I bought the collection last year and had a blast with 1 and 3. 2 was hilariously bad, as expected.
If you are more interested in checking out the extra features of the switch port rather than playing 1, then go for it.
1 is good, however I do feel that 3SE on Switch is much more appealing with the real time style switching and additional features not found anywhere else.
I'd say the trilogy on PS4 is worth it more than just DMC 3 on Switch. DMC 1 is still a fantastic game it just has a few rough edges nowadays. You also get DMC3 as well just without as many bells and whistles as the Switch version.
Oh and if you do go with DMC3 on Switch please do not play with on the fly style switching on your first playthrough. I'm gonna sound lame but the game really wasn't designed with on the fly style switching in mind Like 4 and 5 were. So I think it would be best to save that feature for the second play through if you do go with that version
