What is the cheapest game you have purchased? And what is the most you've spent on a game?

Cheapest = Madden 07 for 50 cents so I can get bonus tradein at gamestop.

Most Expensive = $350 for my arcade machine or $100 something for Starcraft 2 limited edition

Cheapest - 1.00$ for indie game bundles.

Most - Probably 50$ for the Valve Complete Pack.

cheapest => fortix 0.99€
most expensive was dead island 50€ :/

In the past few years or so:

Got a few of the $5 games for around $1 during the holiday sale. Forget which I bought then though, I want to say the VVVVV and C'thulhu/Breath double pack (although I think that's like $3 normally).

Haven't spent more than $60 on a game yet, bought StarCraft II and Skyrim last year full price

Cheapest? Your mom, HAHAHA

Seriously now. I guess it's a Humble Inde Bundle that a friend gave to me for 20 cents. And the most expensive is my Bad Company 2 - Pre Oder(Steam) out steam is my Starcraft 2 Limited Edition.

Cheapest - 0.01$ for indie bundle. And most expensive was COD MW3 (around 22$).

Cheapest: I would say Windowsill. And in deals i can say its Killing Floor complete pack.
Most spent: I can say that is an OLD MMORPG i used to play. but atm that would be Saints Row the third. :D
Most expensive: Saints Row: The Third.

cheapest = stranglehold(xbox360) for 50p. was actually pretty good.

most expensive = swtor for £55. not really a star wars fan but i do like mmo's (not wow)

£0.74 ghost master, £30 on Deus Ex HR

I think the cheapest must be an XBOX360 Controller + Kameo for 2 euro

The most expensive is Final Fantasy XIII-2 Crystal Edition around 80-85 pounds

Cheapest: Cthulhu Saves the World during a Steam sale
Most expensive: Deus Ex:HR (45 Euro)

If we're talking about things that aren't in bundles, probably some random NES game I got for a dime at a thrift store.

Most expensive? Probably a Wii game for only $49.99. Only current gen console I have is a Wii, so most new releases are around $49.99... and I probably only bought one or two full priced games. I nearly always wait for sales.

cheapest= faire solitaire (free)
the most expensive was halo 3 the legendary edition. (150€) its prety cool to have the 3 games stored in the "helmet"

Bought Crysis2 for about 40usd 6 months after the release, because i have some extra money that i dont know what to do with and i was a little bit stupid at that time.

Cheapest: Sequence, as a gift for my friend.

Cheapest: Indie Bundle for 1.20 ~something like that
Most Expensive: Fallout 3 Collector's Edition, (U$ 90 with the taxes+deliver)

Killing Floor = $1

4$ for Company of Heroes Complete Pack during a 90% off sale during the fall
60$ for Battlefield 3

I'd say Plants vs Zombies ($2) and the most expensive... well that would be the pre order of L4D2 i think it was $40 or something like that, can't remember

L4D2= $1
Call of Duty MW3 on my own Country $70

Most Expensive: Batman Arkham City: $60.00

Least Expensive: Portal: FREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

To be honest, I haven't purchased a single game from my account. All of them were free. But the most expensive game there would be Batman: Arkham City.
