A Guide To Super Robot Wars
0/ If you don't wanna play/watch something, just don't do it. Don't make up excuses like "I need to know the correct order and ask fans where to start". Or "motion inputs are too difficult". "Learning a character is too hard". People on the internet nowadays constantly think they need a "good" reason to not like something instead of simply saying "I'm not interested". And then they think that you must enjoy things only in the "best" way possible or whatever. Stop being so capitalist brained, Netflix brained, and White brained.
1/ Stop relying on "watch/play order guides" on gaming sites or Youtube. 99% of these nowadays are SEO trash. As in, they were made specifically to game algorithms and get as many clicks and views as possible, without necessarily being informative. Be it for games or anime or manga or anything. And stop being so obsessed with what is "canon" and what isn't. It doesn't matter. Just decide for yourself.
2/ Look at this list of SRW games on Akurasu wiki and click on the games to see which anime series are in it.
2/ Play the SRW game that seem coolest to you. If you loose interest switch to another one.
