the difference in playing FS1 and FSPort is like... umm...
there isnt any other game with a simmilar experience... maybe Escape Velocity: Nova?
anyways, FS1 has worse textures than FSPort and isnt as purty, but as someone said in the FS2 campaing, "No shields, no flak guns, no beam cannons."
FS2 and FS1 are basically on the same engine, FS2's engine was a bit upgraded as opposed to fs1's, but for some reason... i found FS1 much more fullfilling when played. it was... much more immersive. dont know how to say it exactly, but no game pulled me in like FS1. FSPort just... doesnt do it justice, sorry to guys who did their best to SCP-ify it, but it isnt FS1 if it isnt played in 640x480 with its stock textures on a 15" monitor on a Pentium MMX with a 8meg Voodoo2 and a SoundBlaster copy card
silly, i know, but i first played it on such a rig and then later FSPort on this rig... it just isnt... it.
