To trade in or not to trade in.

I picked up Resident Evil 5 last Friday.   I had a pre-order.

When I bought Star Ocean 4 last month, they pitched me a deal where if I pre-ordered RE5 that day, I could buy the game the ay it came out and within that first week, I could bring it back to them for trade in and I would get all of my money back in store credit.

Cost of game, taxes etc.  All of it.

So I got the deal and am now enjoying the game.   I'm almost done with my SP playthrough (the full thing with a co-op partner to boot, fun times).  However, I don't really forsee this being something I really go back to once I'm done. 

Would I get more than a week's play out of the game were I not to trade it in?  Probably.   I could see a good 2-3 week enjoyment out of it.   But it's not something I could come back to over and over again down the line.

So I submit this to you 2Old2Play - Do I get my money back and miss out on an additional few hours of enjoyment or get that extra week or 2 of gameplay and lose half my money in trade-in value.

I could just rent it for 7-8$ cdn at Blockbuster down the line if I really wanted to play it again....hmm..
