Do you collect and keep your games? Or is this a completely disposable bubble gum hobby for you? Coming in at the end of this generation I've been collecting. Every single dang generation I sell all my old games to fund the purchase of a new system and new games. Then a few years or so into the new gen I get the itch to play some of those old games and by the time I get around to trying to reclaim them, they are hard to find or very expensive.
Collecting for the Wii is easy right now, Wii U is fully BC with the Wii, and the Wii library still has ample supply at retailers like Gamespot in the used games section with some really good games for really good prices. By this time next year, it's likely they will start to become harder to find, prices will go up, and no later than the start of 2015, Gamestop will likely stop accepting as trade-ins or selling them.
I've got a good chunk of what I want, at least that is available in my local area, Still looking for a few things like Tatsunoko vs Capcom, KOF Orochi Saga, Dragon's Lair Trilogy, Mad Dog McCree Collection, Silent Hill: Shattered Memories, Fragile, Resident Evil Archives: REmake and RE: Zero, Guilty Gear: Accent Core, Castlevania: Judgement, Lost in Shadow, and a few others. Most of the first party stuff I still want is readily available still, so no hurry there. I already have Prime Trilogy and the Op Rainfall set.
Keep in mind if you think you might want to replay some of these games that PS4 and Xbone are not in any sense BC. At the best on PS4 you may get to stream some PS3 games with Gaikai, but nothing beats actually having the game at your disposal at any time with no strings attached. So if you still have the hardware, you may want to hold onto it. As a final thought, a lot of us had a good bit of digital games this past gen, isn't it odd that the company who seems the farthest behind on this front, Nintendo, is the only one to respect our previous digital purchases and ensure we can bring them forward with us?
Heck, I can still access their previous console/handheld digital games on my new systems and buy and play them. They don't get nearly enough credit for that.
