I finished Frontlines today.
All in all, Frontlines is pretty fun. I found it refreshing to play missions that didn't always have hidden twists and turns or complicated storylines. There's not a crapton of reading messages. Just good ol' FS1 style 'Here's your mission, go kill stuff' fun. I ran into a good number of bugs here and there (nothing major except CTD probably related to the
Turret Hotkey Script) as well as some things that could have used a little spit-shine. However, Frontlines is the closest thing to a TVW I've ever played and I would like to play more of it. However, I would also add a heavy dose of polish to the missions to remove the minor bugs and increase the general presentation by a small amount.
I'd be happy to give more detailed feedback if you want it, but first I wanted to focus on the positive here. It's easy to nitpick all the little things I would have fixed or done differently. Instead I want to encourage you that this was worth your time. The missions were varied and interesting. It definitely felt like the first few missions of FS1. I looooved that. I look forward to seeing what you do next.
