Outdated in terms of what? I don't agree at all. Just because a game isn't blurry 3D, doesn't unqualify it as a bad game. RSE and FR/LG has dated very well, I think. The graphics is sharp and crisp. No need for yet another remake.
Why do you think ORAS exist if Gen 3 isn't considered outdated? GF could've just as easily put RSE on the Wii U Virtual Console like the other GBA games, and yet, they didn't.
And, there are
a lot of things that Gen 3 is missing besides 3D graphics:
- A P/S Split
- More than 50 TMs
- Varied Pokémon movepools
- Day/Night
- Sprites that aren't small, wonky, and inaccurately colored
- Every new evolution and pre-evolution introduced since Gen 4
- 335 of the total National Dex (as of Gen 6)
- Every Ability introduced since Gen 4
- Fairy types
- Mega Evolutions
- Smarter AI
- Roamers that don't have bad IVs (except Emerald)
- Gym Leader rematches (except Emerald)
- E4 rematches (except FRLG)
- A more fleshed-out story
- Playability on any handheld released since the DSi
And, then, you have the many things FRLG, specifically, are missing because of GF's insistence on keeping things "faithful":
- Any kind of clock (and thus, Espeon and Umbreon)
- A reliable source of Berries
- An unselected PC that still exists as a secondary rival
- A regional device like the Pokégear or Pokénav
- Breeding before the E4
- Post-Gen 1 pre/evos before the E4
- Post-Gen 1 Pokémon, in general, before the E4 (even through trading)
- Any kind of side activity like Contests or the Pokéathlon
No, this doesn't necessarily make them bad games, and nothing's stopping you from enjoying them (You realize that you're speaking to someone who still loves to play the old
8-bit games, right?), but it does make them very outdated and thus, unplayable for many people.
