Thanks everyone for the input, ultimately was really just looking for solid reason behind either decision.
Insurance I have, but its super tricky to get them to replace a video game collection, even as well as cataloged as I have it, lots of issues due to so many items. Hopefully I may be moving soon which will solve that problem but limit me on space again.
Thankfully, I have pretty much completed everything I want for older systems, and a bunch of systems I chose not to collect for (anything pre-nes, sega master system etc). I already have all the rpgs, the rare games etc. Therefore collecting for new systems isn't much an issue, I for the most part don't buy many new but am fairly patient and can snag them super cheap a little ways down the road used, only exception being certain collectors editions ill buy day 1. I literally haven't bought a game that wasn't current gen in months, much less looked for any.
Again, not so much as I look at my collection and see dollar signs, I just know that unlike collecting something like bugs, it has value and thus it weighs on my mind a lot whether I should hold on to it or not. Not hurting for money, but I know it will stress me to no end if it dips to soon worthless. I'd say roughly 5% of the games I own did I pay full retail on, I usually had a rule that I would never pay more than 60% of going rates.
As far as filler, id say that least 80% of my collection are solid titles or those that hold nostalgia for me. I could easily collect 5x as many more games for these systems just to have more but I don't. What I need to get through my head is I need to get rid of redundancy, which is just me being anal. For example, I own god of war 1 and 2 for PS2 and both the PSP games, yet I have both of the PS3 collections. Do I need essentially two copies of same game? No, but I like having the originals and the new, don't know why.
Honestly, this may sound stupid, but I think the reason I dwell on it so much is due to my personal life, being busy working etc and most of my friends moved away. My wife just shakes her head, my son is only 4 and I never have anyone over to impress or even enjoy it with. My man cave is me being solo lol. That said, I enjoy the fact I get to share it with you all and have watched it transform over the years, thanks for all of the compliments
