/vr/ - Retro Games

/vr/ I'm in the process of writing my dissertation and the way I like to write is writing in 20-30min blocks with a 5ish minute or so break to play some video games. I'm looking for some games with short levels that would fit that time frame, something that I can pick up and put down regularly. I would like something new having already completed SMW, SMBs, DKCs, NES Kirby, and Genesis Sonics while writing articles.
Preferably not Ninja Gaiden difficultly, as I would like to relax and not get frustrated with that stupid fucking bird, cat, and the guy shooting at me all at once.
I would also prefer 3rd or 4th generation though I'm open to 5th generation games note I have completed the core N64 collectathons (Mario, Banjo, DKC).
Thanks for any suggestions.
