That’s an interesting one, in several aspects:
For one, as you have mentioned, in the past you had to keep a working console around until emulation caught up, but with the last decade, re-releases and remasters, HD remakes or outright reboots have made it essier than ever to get access to a larger share of our libraries w/o having to belt out that ancient X360 or gamecube.
I’d even go so far as to say that the special sales/festivity celebrations surely must have convinced a few studios to translate games that otherwise would have stayed native region only (currently only japanese stuff comes to mind, but i am pretty sure the same thing applied for chinese or EMEA stuff as well), and if only to make up the numbers, so be it, better than letting them (bit-)rot in hell.
Things like easy access to MiSTER and variants surely also count towards the ‘making it def easier to enjoy many games’-stack — with a big HOWEVER attached to it:
Friend of mine has had a raspberry for emulation ready to go, dabbled with emulators on HTPCs, has a MiSTER-flavour and that playdoodle-thing or what is it called, and with each new go at ‘what killer games do i need for platform X?’ i feel like he always falls back into the same pattern, i.e. installing large libraries of games, and never getting around to actually play them/finding new favs, and ending up replaying the old favs of yore, instead of falling in love anew, and finding some new friends.
Maybe that’s why i tend to be a bit careful with games that sink their teeth into me, because i don’t want the experience to be over too soon, or to get fed up with it.
That said, easy answers i can give right off the bat:
Donkey Kong Country
Command & Conquer: Red Alert
REZ
Ikaruga
Katamari (Katamari 1&2, and the X360 one)
F-Zero GX
SotC
Sonic & Allstars Racing (a.k.a Sanic Kart 2)
Split/Second
Nier Automata
Hot Shot Racing
… there a few more, but sth keeps me from putting them on list right away, which is interesting in itself
