Is there a reason to buy PS1 PSN games if you have the original?

[Severance]

compared to PS1 ? or PS1 games played on PS3 ?

if its compared to PS1 then it would look better on HD tvs, but compared to disk ones played on PS3 then i say no there isn't any.

plus you can use remote play on PSP so you can play the disk based PS1 games, but you have to be online and have to have your ps3 on.
