Discover 10 timeless video games from the past that remain absolutely playable today. From Chrono Trigger to DOOM, these classics have aged like fine wine!
Hot damn that's a good list. The only one i never played is AOE2 and i never finshed Chrono Trigger but it was damn good.
Speaking of what's old but holds up amazingly well and plays like a dream.. i played Symphony of the Night for the first time in 2019.. yep that's right. It became one of my favourite games of all time that i replay almost every year. I couldn't believe how good it was. That is almost impossible for me with newer games let alone older ones. Truly a special gem.
The only one I’d disagree with is doom. It shows its age badly I think. After 5 minutes of play these days you put it down.

Tracking the history of the Metroidvania genre all the way back to the fifth generation of consoles. Here are some of the best.
I own none of these games and I have about 8 XBLA titles. Therefore these are not 'must own', at least to me anyway.
Ageis wing was cool when it was free. I dont know if it still is but I recall getting it and playing with 3 other people online and forming the different ships. I have not played it in some time but it is cool none the less.
Castle crashers and braid are two MUST have games. Those are fun in their own respected ways. SOTN is a PS1 classic that most castlevania fans pretty much already have. Although it does have some smoothed out gfx.
Portal is part of the orange box but this version is nice for those who did not get the whole package. Oddly, I got the orange box for $15 new from target which makes that a better deal than just portal by itself.
Tastes will always differ and while these games are good I wouldnt rank them all as "must own". My tastes are a bit older and I like arcade type games like after burner climax which is half price right now (grrrrr I paid full price). I would love to see sega bring out a daytona or a new thunderblade for xbla/psn.
Some other great xbla games to consider would be shadow complex, pacman championship ed, geowars2 and a long forgotten multiplayer fun game called undertow.
There are many more but i can see with this list he is sharing his tastes with everyone else.
toy soldiers should be on the list, i've had more fun with it than alot of full priced releases.
splosion man,shadow complex, and trails hd.
man i got like 20 xbla titles i say trails hd is now my favorite
