You've got to be kidding me.
They were the first ever remakes and set the standard until HG/SS came along and became the gold standard.
FR/GR gave Kanto...
Modern day graphics at the time
Gen 3 mechanics/engine/abilities
Post game at a new area, Sevii Islands
Able to catch Johto Pokemon
Able to catching Deoxys (Event)
Able to catch/trade every Pokemon into the games
For being the first remakes on the series, they did a great job.
After 20 years and stellar remakes of Gens 1-3, the Gen 4 remakes are absolute trash. Nothing but HD facelifts with a few enhancements with the Underground, clothing, following feature.
