I am currently in the process of purchasing a PS3, and I have a few ideas of what games I would get off the get-go that are reasonable cheap (I found SFIV for 25 at a local gamestore), but I was wondering if you, the giantbomb loyal, had any ideas of cheap games that i could get for my PS3!!

Ratchet and Clank Future: Tools of Destruction is about 20 or 30. You should definitely pick that up.

awesome! thanks a ton!

Little Big Planet is a great and unique game, Valkyria Chronicles is awesome, but its not for everyone, so research!
 
Also you would be way better off getting SFIV on the 360 if you have it, there is a large GB SFIV community, but we all play on the 360 =P
 
I would recommend downloading some games from the playstation store, they have a lot of good ones.
 
Actually check out this blog, it has a good list: The Super Duper PS3 List (of games)
 
 
 
I almost forgot, You should definitely get Disgaea 3 if you like turn based strategy games, that game is probably my favourite game of all time.

ok, awesome, thanks for the tips. I have a 360, so i'll make sure to get it on there. I'm just looking for a somewhat lasting game that will hold me over until i get enough money to start getting more expensive stuff

MGS4 is 20 bucks I think, and Infamous should be about 30 by now

Little Big Planet and MGS 4 are on the cheap side now I think.

The original Uncharted 
 
Dead Space 
 
Killzone 2

MGS4
LBP
Motorstorm
Uncharted
Dead Space
 
and on the PSN:
Wipeout HD
Flower
Fat Princess
Shatter
Super Stardust HD

Little Big Planet & MGS4. I know those two are cheap.

The lack of Demon's Souls in this thread is disturbing.
 
I only recently got a PS3 as well, but I can recommend these:
 
Metal Gear Solid 4
Demon's Souls
Uncharted
Uncharted 2
Killzone 2
 
PSN:
Flower
Noby Noby Boy
