Question about Trades

If they've been bundled in the past or not, you can see if it has via

http://steamgifts.com/bundle-games or from http://isthereanydeal.com/specials/#/search:torchlightii (Torchlight 2 has been bundled 3 times), the last time it was, was 61 days ago in a Weekly Humble Bundle.

The definition of a bundle game is that you had to pay BTA or the latter to get a bunch of games for dirt cheap.

Regardless if you bought them for full or not, the games have been bundled previously in the past.

I'll try my best to explain.

First there are two types of commodities. First raw key. Second gift like you have.

Raw key comes in two types, the first one is from bundles, the second one is retail key. Normally the first and second are of same types, but what differentiates between them is that the latter is more valuable since it's never been bundled e.g from Indiegala or Groupees. if the key comes from those sites (bundles), the value drops considerably. Never expect people to pay more than 1 USD / key if it's a common game like Trine 2 or obscure indies.

Raw keys that are sold from retailers (GMG, GG, Humble etc) but have never been bundled e.g Batman Arkham Knight will hold value depending on market or how good the game is BUT always less than its counterpart in gift form. If it's ROW (rest of world) it will affect the value as well, so you must know what kind of key it is. Region locked whether it's gift or key will make it less valuable.

Now for gifts. Mostly is the same as keys, but benerally traders value gifts more than either raw or retail keys since gifts can be retraded for future profits. Keys, however, are more difficult to track and so people most likely redeem as soon as they get it from traders.

Now in your case, the gifts in your library are gifts indeed, but bundlers like Indiegala or Humbles have been selling them in bundles for cheap prices. Thus, although your gifts are gifts, the copies are more commons and value will be less than you expect - despite you buy it for 20 USD for TL2 for example.

There are people that lowball and prey on unsuspecting/new traders, so watch out. Better ask around than sorry.

I think that's all. Ask away if you want more explanations.
