Question About RPG

I only ever played the card game Sentinels of the Multiverse solo. I had no problem managing all the things in the game on my own I and absolutely love the game and playing it solo. As I've played sentinels, I've fallen in love with the characters and the lore (especially after reading letters page) and I want to continue to follow along with all the characters' journeys. But tactics and the RPG both seem to be multiplayer games and it kills me that there's so much lore to be revealed in both games (especially the RPG) and I can't really play either. It's not that I can't play the game with other people, it's just that no one I know is as into games like this as I am and would enjoy themselves while playing. I've never played an RPG ever, and sentinels was really the first hobby card game I've purchased and bought expansions for (I've since gotten into marvel legendary, another game I'm able to play solo). So is it possible to play the RPG solo, and if not, does anyone have any idea how to continue from the sentinels card game?

It's very difficult to play tabletop RPGs on your own, and although there will occasionally be written modules that do allow someone to sit down and play through an adventure a la a choose your own adventure book, those tend to lack a lot of what makes a tabletop RPG fun, because they essentially railroad you into playing in a certain way. However, I would totally recommend you pick up the RPG anyway, since, in this golden age of the internet, there seems to be a general interest in getting online groups together to play it. If online roleplaying groups aren't your thing, there's Sentinels of Earth Prime, a SotM style card game being designed by Christopher for the folks at Green Ronin and the world of Mutants and Masterminds, and there's Sentinels of Freedom, a tactics video game written for the Sentinels Universe that is on Kickstarter right now.

I hope that helps!

We’ve also started experimenting with play-by-post formats here, and I’m sure that will explode when the actual RPG comes out. I know I’m definitely planning on both running and playing in a campaign when that happens. We should have the process a bit more streamlined by then as well.

I do not like play-by-post, they seem to take to long. But there are some Online communities can one can play with. Roll20.net is a good one and someone made a Character sheet for that. 

There are some people who have hosted (like me) games on Discord and will probably in the future. I am thinking about doing it soon but we will see.

As someone who Demoed this game a ton of times, it is an easy game to teach and most people to get. The starter kits has 90% of the rules you will need and there is a Word doc I have of FAQs that the creator has written to answer the rest. I say get it find some people to play it and give it a go.

I think I've mentioned this earlier, but if not:  I'd be more than willing to run a one-shot now and again via Skype or Google+ Hangouts.  I'd like to wait until at least the PDF of the corebook is out, though, so people can make their own characters.

Also, if I were to get the RPG, what kinds of dice would I need?

You'd need at least 2 standard polyhedral sets (d4, d6, d8, d10, d20) per person playing.  Chessex and Crystal Caste are both great sources for spiffy looking dice.  If you want functional ones and don't care about aesthetics, EAI sells them to educators and Wish has a number of cheap options.

Although if you play online, there are plenty of websites and apps that will do the rolling.  Your GM may have preferences for how you do it.

You could just get a die roller app for your phone, but those aren't as viscerally fun as rolling physical dice.

If I were making dice goodie bags for players, I'd say they need something like: 2d4, 4d6, 3d8, 2d10, 2d12. 

A GM doesn't need a lot of dice, but it helps if they do. I've been gaming for a ridiculously long time, so I've got lots and lots of them. 

Since minions and lieutenants are represented by dice, I put down dry-erase cards (but index cards or post-its work too) with the type of villain, and just put a pile of appropriate dice on it.  

So there might be a card with "Blade Battalion Squad" written on it, with 6d6 (one for each member of the squad). In a bigger fight, there might be multiple cards for multiple squads.  Then I might have another card with "Mobile Defense Platform" on it, with a d10 sitting on it and another with "Omniblade" and a d8.  It's really handy, because when you want that whole Blade Battalion to attack at once, you just pick up all their dice and roll them at the same time. 

And since damage to a minion or lieutenant is represented by shrinking the die type, you'll need plenty of d4s and d6s. If I didn't have lots of dice, I'd use different color poker chips, or pennies and nickels or something like that. 

A person Named Brair made a bot for discord for the purpose to roll dice for this game. I have to find the link and edit it in. (After I ask him)

I asked him and gave me a link.

That's not compltely true, though it takes a bit of extra work to simulate the GM. There's a whole guld on BGG dedicated to soloing popular (and obscure) RPGs.  The key is to find a way of simulating a GM, and there are a number of tools out there that can help with that.

That said it can be a bit much, particularly for someone new to RPGs. 

I've started soloing the Starter Kit adventure, you can find my session notes here if you're interested:   https://boardgamegeek.com/geeklist/241610/item/6207548#item6207548
