Suggestions to start a gaming project

Hey Indiehackers, writing this post today to humbly ask for some advice about a project that I'm about to start in the gaming nice.

Videogames are a big passion of mine, and for this reason I want to see if I can "monetize" this passion to create a project that will look amazing in my personal (and company) portfolio and generate some side income. Especially after meeting recently on Discord a guy that earns 5k to 8k a month by maintaining a gaming statistics website.. Great motivation!

I got a super cool domain: 24hrgaming.com , and I know for sure that I want to generate income (mostly) passively (adsense $ from traffic, print-on-demand merch, premium subscriptions, community sweepstakes, etc... lots of ideas/possibilities).

Obviously monetization comes later, what should be my first concern is pulling constant amount of traffic to my website (webapp. ;P ). My current best idea is to create a news aggregator for gaming, with the ability to personalize your news feed (or just click on some pre-defined feeds like "xbox gaming news" or "console gaming news" or "PC gaming news" or by genre..) and get a mix of news articles, youtube videos, twitch streams, and reddit posts.

The content will be populated from RSS feeds, which probably is bad for SEO since I'm not creating new content that will rank, so should I start thinking about hiring a SEO content writer?

I also won't mind creating video content or streaming on twitch myself. Keep in mind that I'm a developer so I can build pretty much anything I want, I just lack design skills but I was thinking of doing a 99designs brand kit and logo then use these color palettes with a modern React CSS design system like MaterialUI, SemanticUI etc.

Just need to find the real unique value that a news aggregator can provide, or do you think I'm looking too narrow? I really want to start building my first landing page to get leads and test the market, but I want to make sure that I am offering something interesting...

Really looking forward to hear suggestions and some wisdom, thanks for reading all the way :D
