They had a lot of games in that 1 hour though. Sadly most were 2-3 minute cinematic trailers, but at least they were realtime and not CG.
- Ratchet
- Demon Souls
- Horizon
- Miles
- GT7
- Returnal
- Pragmata
- Forspoken
- Deathloop
Of all these games, only ratchet got a gameplay demo which I think will be saved for spiderman. Returnal, GT7, Forspoken and Deathloop had some gameplay snippets, but no 4-5 minutes demo.
- Spiderman 2 - demo
- Wolverine - realtime trailer
- TLOU Factions - realtime trailer with gameplay snippets
- SSM new IP teaser - realtime teaser
- TLOU3 teaser - realtime teaser
- MGS3 - trailer with gameplay snippets
- Silent Hill 2 - trailer with gameplay snippets
- Death Stranding 2 - trailer with gameplay snippets though kojima has been very quiet so maybe hes skipping e3.
- Rise Of Ronin - trailer with gameplay snippets just like last year.
IIRC, there were some developers who took up a lot of time selling various PS5 features. I dont see that happening this time which should allow for even more games. The E3 2015 show had three 5-10 gameplay demos of Horizon, The Last Guardian, Blops 3, and Uncharted 4. The rest were trailers. It was an hour and a half.
